Raghu Angadi commented on HADOOP-3382:
--------------------------------------
TestMiniMRBingUp failes. This is very simple test and does not even use DFS.
The failure seems to another case of HADOOP-3354 (thanks Lohit). I think this
patch can be committed.
> Memory leak when files are not cleanly closed

> {{FSNamesystem.internalReleaseCreate()}} in invoked on files that are open
> for writing but not cleanly closed. e.g. when client invokes
> {{abandonFileInProgress()}} or when lease expires. It deletes the last block
> if it has a length of zero. The block is deleted from the file INode but not
> from {{blocksMap}}. Then leaves a reference to such file until NameNode is
> restarted. When this happens HADOOP-3381 multiplies amount of memory leak.
