Adam J Shook created ACCUMULO-4787: -------------------------------------- Summary: Numerous leaked CLOSE_WAIT threads from TabletServer Key: ACCUMULO-4787 URL: https://issues.apache.org/jira/browse/ACCUMULO-4787 Project: Accumulo Issue Type: Bug Affects Versions: 1.8.1 Environment: * Ubuntu 14.04 * HDFS 2.6.0 and 2.5.0 (in the middle of an upgrade cycle) * ZooKeeper 3.4.6 * Accumulo 1.8.1 * HotSpot 1.8.0_121 Reporter: Adam J Shook Assignee: Adam J Shook
I'm running into an issue across all environments where TabletServers are occupying a large number of ports in a CLOSED_WAIT state writing to a DataNode at port 50010. I'm seeing numbers from around 12,000 to 20,000 ports. In some instances, there were over 68k and it was affecting other applications from getting a free port and they would fail to start (which is how we found this in the first place). -- This message was sent by Atlassian JIRA (v7.6.3#76005)
