Eugene Koontz updated HBASE-3861: --------------------------------- Release Note: added new patch with numClientCnxns set to 5000 (enough for TestHCM to pass). Status: Patch Available (was: Open) > 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 > > 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. -- This message is automatically generated by JIRA.
