liang xie created HADOOP-9181: --------------------------------- Summary: Set daemon flag for HttpServer's QueuedThreadPool Key: HADOOP-9181 URL: https://issues.apache.org/jira/browse/HADOOP-9181 Project: Hadoop Common Issue Type: Bug Affects Versions: 2.0.2-alpha, 3.0.0 Reporter: liang xie
we hit HBASE-6031 again, after looking into thread dump, it was caused by the threads from QueuedThreadPool are user thread, not daemon thread, so the hbase shutdownhook never be called and the hbase instance was hung. Furthermore, i saw daemon be set in fb-20 branch, let's set in trunk codebase as well, it should be safe:) -- This message is automatically generated by JIRA.
