Ayush Saxena commented on HDFS-15076:
-------------------------------------
Thanx [~shv] for the patch, Overall LGTM, Minor doubt :
{code:java}
+ final boolean[] deleted = new boolean[]{false};{code}
Why array of size 1 rather than just having a single variable.
> Fix tests that hold FSDirectory lock, without holding FSNamesystem lock.
