Hadoop Lab Now Available

I was really surprised at the turn-out for JavaOne this year. Judging by the packed halls and empty goodie carts, I think the conference organizers were a little surprised as well. Excellent! Well done.

As you may have noticed, I always seem to have my fingers in the JavaOne hands-on labs pie. This year my contribution was to bring Cloudera into the fold to run a Hadoop lab. Needless to say, that generated a lot of interest. Well before the conference, the slot we had for the lab was booked solid. Taking that as a sign, I had the conference organizers give us a second slot on Monday for the lab. That slot was also booked solid before the conference even began. Unfortunately, however, that Monday lab slot ended up getting canceled for <INSERT OFFICIAL REASON HERE>. As a concession to the folks who didn't get to attend because of the cancellation, I got the conference organizers to give me permission to have Cloudera host the lab materials from their site before it's available from the official Oracle JavaOne site.

You can find the semi-official JavaOne Hands-on Lab S314413: Extracting Real Value from Your Data With Apache Hadoop here under the training section of the Cloudera site. The file is not yet linked from anywhere but here, but they're working on it.

If you download the zip file, in it you will find a lab workbook. At the back of the workbook, you will find an appendix that describes how to set up your own lab environment. The lab was written for Solaris 11 Express and NetBeans, but the OS and IDE really play little role in the lab. If you refuse to see the light and accept Solaris as the one true OS, you can still do the lab on some other OS with some other IDE (but it won't be as satisfying).

The lab did run in its originally assigned slot at JavaOne, and it was really successful. Turnout was good and the comments were great! I've already incorporated lots of great feedback from that session into the lab materials that Cloudera is now hosting, but I'm always happy to hear any additional comments and/or feedback. Happy coding!

JavaOne Hands-on Labs Online

In case you haven't noticed yet, we've posted the JavaOne Hands-on Labs from this year to Among the labs posted there are the Compute Server lab (7410), which includes my old DRMAA lab as an appendix, and the Project Darkstar lab (7400). If you missed them at JavaOne, now's your chance to do them from the comfort of home.

JavaOne 12: Friday AM

Friday started with a 2-hour keynote where James Gosling showed a bunch of technology demos, ranging from developer tools to toys to industrial robots. Neat stuff. Suspiciously missing, though, was the winner of the slotcar challenge. Wonder what's up with that...

After the keynote, I put my nose to the grindstone and (finally) hit the sessions hard. First up, Effective Concurrency For the Java™ Platform (TS-2388). As Brian pointed out several times, none of the content was riveting and new, but it pointed out common fallacies and errors. Definitely worth checking out when the content goes online.

And that does it for the AM...

JavaOne 12: Thursday PM

Even though the Darkstar lab was Wednesday night, Thursday morning it was still consuming my time. You see, the fifth exercise in the lab was to extend the MUD in new and creative ways and check in the results. I spent Thursday morning with Jeff assembling the contributions so that we can post them online.

The excuses continue. Between lunch with co-workers, dinner with the Darkstar (et al) team, and various hallway conversations, I only made it to 1/4 of a session on Thursday. I'm kinda bummed about that, but I think this year the social side of JavaOne is more important for me. I'll do better on Friday.

I did catch the last hour of the After Dark event. Not bad. They trucked in a bunch of the champion Battlebots from the television show and let folks from the conference drive them. Gratuitous fun. They closed the night with a Rolling Stones cover band who was decent. Would have been better if the beer weren't so bad.

JavaOne 12: Wednesday PM

I had to be back in Palo Alto for personal reasons on Wednesday morning, so I didn't get back to the conference until the late afternoon. After dealing with some last-minute issues with the Darkstar lab, I went to the Intel general session. Less than thrilling. The Intel spokewoman gave a long spiel on how wonderful Intel chips are and wanted everyone to know that Intel is working with Sun to make sure that Java runs best on Intel. For me there were only two interesting points: 1) Intel has already shipped 1 million quad-core units, whereas AMD hasn't shipped 1, and 2) Intel will provide an Itanium port for Java, and Sun will host it on

After the general session, I caught the NIO talk (TS-2992). What I learned is that I don't know jack about NIO. The 6 tips and tricks the speakers presented didn't mean a thing to me. Oh, well

After that I went to the Java performance BOF (BOF-2366), where people asked very specific questions about API's haven't had a reason to use. What's up with that? I used to be Java savvy. I guess I just haven't had a reason to use some of the newer, deeper APIs yet. That's the trouble with being on the engineering team for a C-based product.

I had to leave the BOF early to be at the Darkstar lab 20 minutes early. The lab went really well. All of the feedback I got was extremely positive. As far as I can tell, we hit it out of the park. Even though the lab was scheduled to end at 22:45, we ended up staying until 0:15. People just didn't want to leave!

JavaOne 12: Tuesday AM

Welcome to JavaOne! There's a lot of people here! Looking at the schedule, the content looks great.

General Session

  • The JDK is now completely open. (There are actually a couple of small pieces that we couldn't open up yet, but you can get binaries plugs for those pieces until we can get them opened.)
  • The governance model for the JDK community was announced. The board will be Doug Lea, Fabiane Nardon, Simon Phipps, Mark Reinhold, and Dalibor Topič
  • The TCK will also be make available for use by the community.
  • The next several releases of JDK 6 will be focused on execution and startup speed.
  • Rich announced JavaFX, which is a new family of technologies and tools that make it easier to use Java in the consumer space. The first piece is JavaFX Script, formerly known as F3. Consider it a competitor to Flash. The second piece is JavaFX Mobile, which is our new name for the SavaJe technology we recently acquired. It's approximately Java SE for handsets. (Believe it or not, we actually had a female engineer demo JavaFX Mobile on stage!)
  • McNeally talked about Curriki, his pet project for providing free K-12 educational materials online.

And the on-going saga of the Darkstar hands-on lab ate up a couple more hours of my day. Between that, being a proctor for the Realtime Java hands-on-lab, and hanging out in the pavilion, I didn't actually make it to a single session today. Shame on me.

JavaOne 12: Monday PM

Unfortunately, I was only able to go to one session this afternoon. It was the session on the new NetBeans 6.0 features. One word: WOW! I can't freaking wait! Apparently the 6.0 preview release is now available. 6.0 is going to completely change the game.

After the session I had to go try to get the Darkstar lab (LAB-7210, Wednesday at 20:45) in ship shape. Still not done, but I think I've got it on the ropes.

JavaOne 12: Monday AM

Like last year, I will be blogging JavaOne again. Fortunately, all the JavaOne materials will be available online after the conference. For the lazy and/or impatient, I will be blogging my summary of the points that I found interesting in the sessions that I attended.

Today I'm attending the CommunityOne JavaOne pre-conference (AKA NetBeans Day).

General Session

  • According to an EU-funded study, Sun is the number one contributor of open source code in the world. More notably, we have contributed three times the number of lines of codes as the number two contributor, IBM.
  • Tim O'Reilly pointed out that while the major Internet properties are based on open-source technologies, almost none of them are themselves open source.
  • Tim O'Reilly's definition of "Web 3.0" is where it builds on the emerging data streams that aren't explicitly provided by the user, such as GPS data, gestural interfaces, etc.
  • Sun is considering how to compensate developers for open source materials that we monetize.
  • Tim O'Reilly reminds me of Dennis Hopper now that he wears a beard.

NetBeans General Session

  • Rich Green reiterated that we need to look at how to compensate the authors of open source content that we're able to monetize. "I'm sure we're going to do that... Real soon now," he said.
  • For Sun, going balls-to-the-wall open source is really just us returning to our roots and re-establishing two-way communications with our developers.
  • Schwartz on Eclipse: "THey may have more market share, but our developers have more fun." He said that we're not concerned with Eclispe. They're our "brothers in arms" against "someone else." In general, the competition has been good for us, and we're really doing well. We hope to be dominant, but we don't want to kill them.
  • There's an plugin for NetBeans for developing OOo extensions.

That's it for now. I'm off to lunch. Look for more this evening.
