stack commented on HBASE-12645:
-------------------------------
If they are using HBaseTestingUtility, they should use its means of creating
dirs for test data. It has facility for doing cleanup. Also makes dirs in
right location, under target. Ideally, when test suite has finished, there is
no test data or logs outside of the module target dir. You may not be able to
force this. IIRC, minihdfs is not completely configurable and can write
outside test dir but it is a while since I looked at it. Good luck.
> HBaseTestingUtility is using ${$HOME} for rootDir
