Sylvain Lebresne commented on CASSANDRA-7241:
---------------------------------------------
If others run into that NPE in MiniDFSCluster.startDataNodes, the
problem/solution is explained
[here|http://stackoverflow.com/questions/17625938/hbase-minidfscluster-java-fails-in-certain-environments].
With that fixed, I do get the same testCqlStorageCompositeKeyTable failure.
That said, when starting to look into what's going on, I added one simple log
statement in ModificationStatement to log the applied mutation, and somehow
that was enough to make the test pass some of the times (not every time, but
often enough). So it's a timing issue, probably something that's not really
related to CASSANDRA-5417 but was exposed by it because the timing changed.
Where to go from there, I'm not sure. I have zero experience with Pig or Hadoop
and our integration of it, and I have a hard time wrapping my head around the
CqlStorage/AbstractCassandraStorage code tbh, so I'm not sure I'm the most
qualified person to track this race down. But given that the pig test seems to
be the only ones having problem of that sort, it suggests (though I can't be
sure) that said race is more likely in either the pig code or the pig tests
than anything else.
So I'm going to unassigned myself for now because I just don't have the time
and experience to dig into the pig layers. If someone more familiar with those
is able to reduce the failure to something Cassandra specific, I'll gladly take
a look at that.
