> 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.
