Xiaoyu Yao updated HADOOP-12950: -------------------------------- Attachment: HADOOP-12950.04.patch Thanks [~jingzhao]! Patch v04 attached based on your comments. > 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 > Attachments: HADOOP-12950.00.patch, HADOOP-12950.01.patch, > HADOOP-12950.02.patch, HADOOP-12950.03.patch, HADOOP-12950.04.patch > > > 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)
