Attachment: hbase-14598-v1.patch
> ByteBufferOutputStream grows its HeapByteBuffer beyond JVM limitations
> ----------------------------------------------------------------------
>
> Key: HBASE-14598
> URL: https://issues.apache.org/jira/browse/HBASE-14598
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.98.12
> Reporter: Ian Friedman
> Assignee: Ian Friedman
> Attachments: 14598.txt, hbase-14598-v1.patch
>
>
> We noticed that in returning a Scan against a region containing particularly
> large (wide) rows that it is possible during
> ByteBufferOutputStream.checkSizeAndGrow() to attempt to create a new
> ByteBuffer larger than the JVM allows which then throws a OutOfMemoryError.
> The code currently caps it at Integer.MAX_VALUE which is actually larger than
> the JVM allows. This lead to us dealing with cascading region server death as
> the RegionServer hosting the region died, opened on a new server, the client
> retried the scan, and the new RS died as well.
> I believe ByteBufferOutputStream should not try to create ByteBuffers that
> large and instead throw an exception back up if it needs to grow any bigger.
> The limit should probably be something like Integer.MAX_VALUE-8, as that is
> what ArrayList uses. ref:
