liang xie commented on HBASE-6727: ---------------------------------- Hi Kannan, can we close it now, since i saw "Revision: 1395033" had resolved it on FB-89 branch. > [89-fb] allow HBaseServers's callqueue to be better configurable to avoid OOMs > ------------------------------------------------------------------------------ > > Key: HBASE-6727 > URL: https://issues.apache.org/jira/browse/HBASE-6727 > Project: HBase > Issue Type: Bug > Reporter: Kannan Muthukkaruppan > Assignee: Michal Gregorczyk > > The callQueue size (where requests get queued up if all handlers are busy) is > a LinkedBlockingQueue of size 100 * number_of_handlers. So, with say 300 > handler threads, the call queue can have upto 30k entries queued up. If the > requests are large enough, this can result in OOM or severe GC pauses. > Ideally, we should allow this param to be separately configurable independent > of the numberof handlers; perhaps an even better approach would be to specify > a memory size based limit, instead of a number of entries based limit. > [I have not looked at the trunk version for this issue. So it may or may not > be relevant there.] -- This message is automatically generated by JIRA.
