This is because Mesos calls it with a different environment or something, the result is that the Spark jar is missing and it can't load classes.
This fixes http://apache-spark-user-list.1001560.n3.nabble.com/java-lang-ClassNotFoundException-spark-on-mesos-td3510.html
I have no idea whether this is the right fix, I can only confirm that it fixes the issue for us.
The `registered` method is called from mesos (765ff9bc2a/src/java/jni/org_apache_mesos_MesosExecutorDriver.cpp)
I am unsure which commit caused this regression

This PR may still overstep what you have in mind, but let me put it on the table to start. Besides fixing the issue, it has one substantive change, and that is to manage Hadoop-specific things only in Hadoop-related profiles. This does _not_ remove `yarn.version`.
- Moves the YARN and Hadoop profiles together in pom.xml. Sorry that this makes the diff a little hard to grok but the changes are only as follows.
- Removes `hadoop.major.version`
- Introduce `hadoop-2.2` and `hadoop-2.3` profiles to control Hadoop-specific changes:
- like the protobuf version issue - this was only 'solved' now by enabling YARN for 2.2+, which is really an orthogonal issue
- like the jets3t version issue now
- Hadoop profiles set an appropriate default `hadoop.version`, that can be overridden
- _(YARN profiles in the parent now only exist to add the sub-module)_
- Fixes the jets3t dependency issue
- and makes it a runtime dependency
- and centralizes config of this guy in the parent pom
- Updates build docs
- Updates SBT build too
- and fixes a regex problem along the way

I tested the change locally with Spark 0.9.1, but I can't test with 1.0.0 because there was no AMI for it at the time. It's a trivial fix, so it shouldn't cause any problems.

I gave the Streaming code examples, both Scala and Java, a test run today. I turned up a number of small errors, mostly compile errors in the Java examples. There were a few typos in the Scala too.
I also took the liberty of adding things like imports, since in several cases they are not obvious. Feel free to push back on some changes.
There's one thing I haven't quite addressed in the changes. `JavaPairDStream` uses the Java API version of `Function2` in almost all cases, as `JFunction2`. However it uses `scala.Function2` in:
```
def reduceByKeyAndWindow(reduceFunc: Function2[V, V, V], windowDuration: Duration)
:JavaPairDStream[K, V] = {
dstream.reduceByKeyAndWindow(reduceFunc, windowDuration)
}
```
Is that a typo?
Also, in Scala, I could not get this to compile:
```
val windowedWordCounts = pairs.reduceByKeyAndWindow(_ + _, Seconds(30), Seconds(10))
error: missing parameter type for expanded function ((x$1, x$2) => x$1.$plus(x$2))
```
You can see my fix below but am I missing something?
Otherwise I can say these all worked for me!

This change replaces some Scala `for` and `foreach` constructs with `while` constructs. There may be a slight performance gain on the order of 1-2% when training an ALS model.
I trained an ALS model on the Movielens 10M-rating dataset repeatedly both with and without these changes. All 7 runs in both columns were done in a Scala `for` loop like this:
for (iter <- 0 to 10) {
val before = System.currentTimeMillis()
val model = ALS.train(rats, 20, 10)
val after = System.currentTimeMillis()
println("%d ms".format(after-before))
println("rmse %g".format(computeRmse(model, rats, numRatings)))
}
The timings were done on a multiuser machine, and I stopped one set of timings after 7 had been completed. It would be nice if somebody with dedicated hardware could confirm my timings.
After Before
121980 ms 122041 ms
117069 ms 117127 ms
115332 ms 117523 ms
115381 ms 117402 ms
114635 ms 116550 ms
114140 ms 114076 ms
112993 ms 117200 ms
Ratios are about 1.0005, 1.0005, 1.019, 1.0175, 1.01671, 0.99944, and 1.03723. I therefore suspect these changes make for a slight performance gain on the order of 1-2%.
