Subject [jira] [Commented] (HBASE-13188) java.lang.ArithmeticException issue in BoundedByteBufferPool.putBuffer
Date Thu, 19 Mar 2015 12:33:39 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13188?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14369261#comment-14369261
] 

Nicolas Liochon commented on HBASE-13188:
-----------------------------------------

[~saint.ack@gmail.com] if you're interested, there is a ByteBufferPool in HBASE-9535. If I
understand well 9535 is now irrelevant (please close it if it's the case), but may be there
is some code to take there.

> I checked in the trunk code also.  I think the comment in the code suggests that the
size will not be exact so there is a chance that it could be even 0.
