> We're seeing a lot of issues with hadoop-qa related to threads or file descriptors.
> Monitoring these counters would ease the analysis.
> Note as well that
>  - if we want to execute the tests in the same jvm (because the test is small or because
we want to share the cluster) we can't afford to leak too many resources
>  - if the tests leak, it's more difficult to detect a leak in the software itself.
> I attach piece of code that I used. It requires two lines in a unit test class to:
> - before every test, count the threads and the open file descriptor
> - after every test, compare with the previous value.
> I ran it on some tests; we have for example:
> - client.TestMultiParallel#testBatchWithManyColsInOneRowGetAndPut: 232 threads (was 231),
390 file descriptors (was 390). => TestMultiParallel uses 232 threads!
> - client.TestMultipleTimestamps#testWithColumnDeletes: 152 threads (was 151), 283 file
descriptors (was 282).
> - client.TestAdmin#testCheckHBaseAvailableClosesConnection: 477 threads (was 294), 815
file descriptors (was 461)
> - client.TestMetaMigrationRemovingHTD#testMetaMigration: 149 threads (was 148), 310 file
descriptors (was 307).
> It's not always leaks, we can expect some pooling effects. But still...
