Kevin Risden commented on SOLR-5007:
------------------------------------
I think I found the underlying issue. FileContext.getFileContext doesn't close
the underlying filesystem that gets created. There is a rename method now on
the Filesystem that gets closed correctly. I am trying to track down when the
rename method was added to Filesystem class.
I need to run all the HDFS related tests to make sure nothing is broken but
this fixed the IPC thread issue with a few of the tests (TestRecoveryHdfs,
HdfsDirectoryFactoryTest, HdfsDirectoryTest).
> TestRecoveryHdfs seems to be leaking a thread occasionally that ends up
> failing a completely different test.
