-----------------------------------
Summary: ShutdownHookManager should have a timeout for each of the
Registered shutdown hook
Key: HADOOP-12950
URL: https://issues.apache.org/jira/browse/HADOOP-12950
Project: Hadoop Common
Issue Type: Improvement
Reporter: Xiaoyu Yao
Assignee: Xiaoyu Yao
HADOOP-8325 added a ShutdownHookManager to be used by different components
instead of the JVM shutdownhook. For each of the shutdown hook registered, we
currently don't have an upper bound for its execution time. We have seen
namenode failed to shutdown completely (waiting for shutdown hook to finish
after failover) for a long period of time, which breaks the namenode high
availability scenarios. This ticket is opened to allow specifying a timeout
value for the registered shutdown hook.
