[jira] [Created] (HBASE-13733) failed MiniZooKeeperCluster startup
not shut down ZK servers
Stephen Yuan Jiang created HBASE-13733:
------------------------------------------
Summary: failed MiniZooKeeperCluster startup not shut down ZK servers
Key: HBASE-13733
URL: https://issues.apache.org/jira/browse/HBASE-13733
Project: HBase
Issue Type: Bug
Components: Zookeeper
Affects Versions: 1.1.0, 2.0.0, 1.2.0
Reporter: Stephen Yuan Jiang
Assignee: Stephen Yuan Jiang
MiniZooKeeperCluster#startup() starts servers one-by-one, if everything is good, it would declare success of start:
{code}
public int startup(File baseDir, int numZooKeeperServers)
...
// running all the ZK servers
for (int i = 0; i < numZooKeeperServers; i++) {
...===> could throw exception in the loop and end the startup
// Start up this ZK server
standaloneServerFactory.startup(server);
...
standaloneServerFactoryList.add(standaloneServerFactory);
zooKeeperServers.add(server);
}
...
started = true;
...
}
{code}
However, if exception throws in the middle of start up (eg. some servers already started), the MiniZooKeeperCluster#shutdown() would not shut down them and clean up resources.
{code}
public void shutdown() throws IOException {
if (!started) {
return;
}
...
}
{code}
