---------------------------------
Summary: ThriftServer leaks ZooKeeper connections
Key: HBASE-13437
URL: https://issues.apache.org/jira/browse/HBASE-13437
Project: HBase
Issue Type: Bug
Components: Thrift
Affects Versions: 0.98.8
Reporter: punwinger
HBase ThriftServer will cache Zookeeper connection in memory using
org.apache.hadoop.hbase.util.ConnectionCache. This class has a mechanism called
chore to clean up connections idle for too long(default is 10 min). But method
timedOut for testing whether idle exceed for maxIdleTime always return false
which leads to never release the Zookeeper connection. If we send requestto
ThriftServer every maxIdleTime then ThriftServer will keep thousands of
Zookeeper Connection soon.
