Allen Wittenauer updated HDFS-12711:
------------------------------------
Resolution: Incomplete
Status: Resolved (was: Patch Available)
I think I'm going to close this as incomplete. Yetus 0.7.0 and up appear to be
successfully preventing HDFS unit tests from killing nodes. It does not,
however, make the HDFS unit tests work. They are still wildly unreliable (e.g.,
HDFS-12512).
There are two remediations that need to happen, both of which are out of my
purview:
1. The Hadoop PMC needs to push on INFRA-15685 to get the max task count
raised. Doing so raises the thread count, but that's only a *temporary*
solution until HDFS is pushed over the edge again.
2. hadoop-hdfs-project either needs to get refactored into multiple maven
modules or the simultaneous thread counts need to get greatly reduced. e.g.,
just changing the unit test's DN RPC thread count may work.
