Xiaoyu Yao created HADOOP-12950: ----------------------------------- 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
