Enis Soztutar commented on HBASE-7911:
--------------------------------------
bq. The only way I can see a NullPointerException looking at the code is that
the parent node doesn't exists and listChildren() returns null
Yes, it seems that we are getting the NPE because znode children returns null.
We do create the parent node in ctor of ZKInterProcessLockBase, so it should be
some race condition.
