Deadlock in metrics ------------------- Key: HADOOP-8050 URL: https://issues.apache.org/jira/browse/HADOOP-8050 Project: Hadoop Common Issue Type: Bug Components: metrics Affects Versions: 1.0.0, 0.20.205.0, 0.20.204.0 Reporter: Kihwal Lee Fix For: 1.1.0, 1.0.1
The metrics serving thread and the periodic snapshot thread can deadlock. It happened a few times on one of namenode we have. When it happens RPC works but the web ui and hftp stop working. I haven't look at the trunk too closely, but it might happen there too. -- This message is automatically generated by JIRA.
