------------------------------
Summary: ShutdownHook should check whether shutdown hook is
tracked by ShutdownHookManager
Key: HBASE-19954
URL: https://issues.apache.org/jira/browse/HBASE-19954
Project: HBase
Issue Type: Bug
Reporter: Ted Yu
Assignee: Ted Yu
Currently ShutdownHook#suppressHdfsShutdownHook() does the following:
{code}
synchronized (fsShutdownHooks) {
boolean isFSCacheDisabled =
fs.getConf().getBoolean("fs.hdfs.impl.disable.cache", false);
if (!isFSCacheDisabled &&
!fsShutdownHooks.containsKey(hdfsClientFinalizer)
&& !ShutdownHookManager.deleteShutdownHook(hdfsClientFinalizer)) {
{code}
There is no check that ShutdownHookManager still tracks the shutdown hook,
leading to potential RuntimeException (as can be observed in hadoop3 Jenkins
job).
