Hiroshi Ikeda created HBASE-15803:
-------------------------------------
Summary: ZooKeeperWatcher's constructor can leak a ZooKeeper
instance with throwing ZooKeeperConnectionException when canCreateBaseZNode is
true
Key: HBASE-15803
URL: https://issues.apache.org/jira/browse/HBASE-15803
Project: HBase
Issue Type: Bug
Reporter: Hiroshi Ikeda
Priority: Minor
{code}
public ZooKeeperWatcher(Configuration conf, String identifier,
Abortable abortable, boolean canCreateBaseZNode)
throws IOException, ZooKeeperConnectionException {
...skip...
this.recoverableZooKeeper = ZKUtil.connect(...
...skip...
if (canCreateBaseZNode) {
createBaseZNodes();
}
}
private void createBaseZNodes() throws ZooKeeperConnectionException {
{code}
The registered watcher doesn't seem to close the Zookeeper instance by watch
events, and the instance keeps alive when createBaseZNodes is failed.
