[jira] [Reopened] (HBASE-3861) MiniZooKeeperCluster.startup()
should refer to hbase.zookeeper.property.maxClientCnxns
[ https://issues.apache.org/jira/browse/HBASE-3861?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andrew Purtell reopened HBASE-3861:
-----------------------------------
Caused TestHCM to OOME on trunk up on Jenkins. Backed out for now. Reopening to investigate / fix.
> MiniZooKeeperCluster.startup() should refer to hbase.zookeeper.property.maxClientCnxns

> Key: HBASE-3861
> URL: https://issues.apache.org/jira/browse/HBASE-3861
> Project: HBase
> Issue Type: Improvement
> Affects Versions: 0.90.3
> Reporter: Eugene Koontz
> Assignee: Eugene Koontz
> Fix For: 0.90.3, 0.92.0
>
> Attachments: HBASE-3861.patch, HBASE-3861.patch
>
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> Currently the number of the client connections is hard-wired to 1000:
> {{{
> standaloneServerFactory = new NIOServerCnxnFactory();
> standaloneServerFactory.configure(new InetSocketAddress(clientPort),1000);
> } catch (BindException e) {
>
> }}}
> This should be set according to the test environment's hbase configuration. The property in
> question is : hbase.zookeeper.property.maxClientCnxns.
> Currently some tests such as org.apache.hadoop.hbase.client.TestHCM fail because the number of connections used by the HBase client exceeds 1000.
> Recently MAX_CACHED_HBASE_INSTANCES increased from 31 to 2000 on 0.90 branch:
> http://svn.apache.org/viewvc/hbase/branches/0.90/src/main/java/org/apache/hadoop/hbase/client/HConnectionManager.java?p2=%2Fhbase%2Fbranches%2F0.90%2Fsrc%2Fmain%2Fjava%2Forg%2Fapache%2Fhadoop%2Fhbase%2Fclient%2FHConnectionManager.java&p1=%2Fhbase%2Fbranches%2F0.90%2Fsrc%2Fmain%2Fjava%2Forg%2Fapache%2Fhadoop%2Fhbase%2Fclient%2FHConnectionManager.java&r1=1096818&r2=1096817&view=diff&pathrev=1096818
> and correspondingly the hbase config on the Zookeeper server-side also increased in hbase-default.xml:
> http://svn.apache.org/viewvc/hbase/branches/0.90/src/main/resources/hbase-default.xml?p2=%2Fhbase%2Fbranches%2F0.90%2Fsrc%2Fmain%2Fresources%2Fhbase-default.xml&p1=%2Fhbase%2Fbranches%2F0.90%2Fsrc%2Fmain%2Fresources%2Fhbase-default.xml&r1=1091594&r2=1091593&view=diff&pathrev=1091594
> So if MiniZKCluster looks at this setting, the test won't have this failure.
