nkeywal commented on HBASE-5064:
--------------------------------
I've seen something. If it's not the problem, it is a problem.
On hadoop QA, we have
max user processes (-u) 2048
Try this on you computer:
ulimit -u 256
Then run a test such as TestAdmin
You will have a nice java.lang.OutOfMemoryError: unable to create new native
thread
This because this limit controls not only the number of processes but as well
the number of native threads.
We should have this set to a much bigger value.
> use surefire tests parallelization
