Josh Rosen updated SPARK-9035:
------------------------------
Description:
There is an issue trying to run Spark on Mesos (using MapRFS). I am able to
run this in YARN (Using Myriad on Mesos) on the same cluster, just not directly
on Mesos. I've corresponded with MapR and the issue appears to be the class
loader being NULL. They will look at trying to address it in their code as
well, but the issue exists here as the desired behavior shouldn't be to pass
NULL (see https://issues.apache.org/jira/browse/SPARK-1403) Note, I did try to
work to reopen SPARK-1403 and Patrick Wendell asked me to open a new issue,
(that is this JIRA).
Environment:
MapR 4.1.0 (using MapRFS)
Mesos 22.1
Spark 1.4 (The issue occurs on Spark 1.3.1, 1.3.0, 1.2.2 but not 1.2.0)
Some comments from Kannan at MapR (he is no longer with MapR, these comments
were prior to him leaving:
Here is the corresponding ShimLoader code. cl.getParent is hitting NPE.
If you look at Spark code base, you can see that the setContextClassLoader is
invoked in a few places, but not necessarily in the context of this stack trace.
{code}
private static ClassLoader getRootClassLoader() {
ClassLoader cl = Thread.currentThread().getContextClassLoader();
trace("getRootClassLoader: thread classLoader is '%s'",
cl.getClass().getCanonicalName());
while (cl.getParent() != null) {
cl = cl.getParent();
}
trace("getRootClassLoader: root classLoader is '%s'",
cl.getClass().getCanonicalName());
return cl;
}
{code}
MapR cannot handle NULL in this case. Basically, it is trying to get a root
classloader to use for loading a bunch of classes. It uses the thread's context
class loader (TCCL) and keeps going up the parent chain. We could fall back to
using the current class's classloader whenever TCCL is NULL. I need to check
with some folks what the impact will be. I don't know the specific reason for
choosing the TCCL here.
I have raised an internal bug to fall back to using the current class loader
if the TCCL is not set. Let us also figure out if there is a way for Spark to
address this - if it is really a change in behavior from their side. I think we
should still fix out code to not make this assumption. But since this is a core
change, it may not get out soon.

> Spark on Mesos Thread Context Class Loader issues
> -------------------------------------------------
>
> Key: SPARK-9035
> URL: https://issues.apache.org/jira/browse/SPARK-9035
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.2.2, 1.3.0, 1.3.1, 1.4.0
> Environment: Mesos on MapRFS.
> Reporter: John Omernik
> Priority: Critical
>
> There is an issue trying to run Spark on Mesos (using MapRFS). I am able to
> run this in YARN (Using Myriad on Mesos) on the same cluster, just not
> directly on Mesos. I've corresponded with MapR and the issue appears to be
> the class loader being NULL. They will look at trying to address it in their
> code as well, but the issue exists here as the desired behavior shouldn't be
> to pass NULL (see https://issues.apache.org/jira/browse/SPARK-1403) Note, I
> did try to work to reopen SPARK-1403 and Patrick Wendell asked me to open a
> new issue, (that is this JIRA).
> Environment:
> MapR 4.1.0 (using MapRFS)
> Mesos 22.1
> Spark 1.4 (The issue occurs on Spark 1.3.1, 1.3.0, 1.2.2 but not 1.2.0)
> Some comments from Kannan at MapR (he is no longer with MapR, these comments
> were prior to him leaving:
> Here is the corresponding ShimLoader code. cl.getParent is hitting NPE.
> If you look at Spark code base, you can see that the setContextClassLoader is
> invoked in a few places, but not necessarily in the context of this stack
> trace.
> {code}
> private static ClassLoader getRootClassLoader() {
> ClassLoader cl = Thread.currentThread().getContextClassLoader();
> trace("getRootClassLoader: thread classLoader is '%s'",
> cl.getClass().getCanonicalName());
> while (cl.getParent() != null) {
> cl = cl.getParent();
> }
> trace("getRootClassLoader: root classLoader is '%s'",
> cl.getClass().getCanonicalName());
> return cl;
> }
> {code}
> MapR cannot handle NULL in this case. Basically, it is trying to get a root
> classloader to use for loading a bunch of classes. It uses the thread's
> context class loader (TCCL) and keeps going up the parent chain. We could
> fall back to using the current class's classloader whenever TCCL is NULL. I
> need to check with some folks what the impact will be. I don't know the
> specific reason for choosing the TCCL here.
> I have raised an internal bug to fall back to using the current class
> loader if the TCCL is not set. Let us also figure out if there is a way for
> Spark to address this - if it is really a change in behavior from their side.
> I think we should still fix out code to not make this assumption. But since
> this is a core change, it may not get out soon.
