Chris Nauroth resolved HDFS-6349.
---------------------------------
Resolution: Duplicate
Hi, [~kihwal]. This same issue is tracked in HDFS-5995, so I'm resolving
HDFS-6349 as duplicate. There is a lot of discussion and a proposed patch on
the other issue, but no concrete resolution yet.

> Key: HDFS-6349
> URL: https://issues.apache.org/jira/browse/HDFS-6349
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 2.5.0
> Reporter: Kihwal Lee
>
> AclEditLogUtil.read() can throw OutOfMemoryException when it encounters a
> certain corrupt entry. This is because it reads the size and blindly tries to
> allocate an ArrayList of that size.
> Because of this a test case always dumps the heap. The test doesn't fail
> since edit log loading catches and "handles" the exception.

> java.lang.OutOfMemoryError: Java heap space
> Dumping heap to java_pid18667.hprof ...
> Heap dump file created \[43870820 bytes in 0.154 secs\]
