Followerhandler should close the socket if it gets an exception on a write. ---------------------------------------------------------------------------
Key: ZOOKEEPER-519 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-519 Project: Zookeeper Issue Type: Bug Reporter: Mahadev konar Fix For: 3.3.0 We noticed this in our tests - {code} java.net.SocketException: Broken pipe at java.net.SocketOutputStream.socketWrite0(Native Method) at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:92) at java.net.SocketOutputStream.write(SocketOutputStream.java:136) at java.io.BufferedOutputStream.write(BufferedOutputStream.java:105) at java.io.DataOutputStream.write(DataOutputStream.java:90) at java.io.FilterOutputStream.write(FilterOutputStream.java:80) at org.apache.jute.BinaryOutputArchive.writeBuffer(BinaryOutputArchive.java:122) at org.apache.zookeeper.server.DataNode.serialize(DataNode.java:126) at org.apache.jute.BinaryOutputArchive.writeRecord(BinaryOutputArchive.java:126) at org.apache.zookeeper.server.DataTree.serializeNode(DataTree.java:878) at org.apache.zookeeper.server.DataTree.serializeNode(DataTree.java:890) at org.apache.zookeeper.server.DataTree.serializeNode(DataTree.java:890) at org.apache.zookeeper.server.DataTree.serializeNode(DataTree.java:890) at org.apache.zookeeper.server.DataTree.serializeNode(DataTree.java:890) at org.apache.zookeeper.server.DataTree.serializeNode(DataTree.java:890) at org.apache.zookeeper.server.DataTree.serialize(DataTree.java:940) at org.apache.zookeeper.server.util.SerializeUtils.serializeSnapshot(SerializeUtils.java:102) at org.apache.zookeeper.server.ZooKeeperServer.serializeSnapshot(ZooKeeperServer.java:269) at org.apache.zookeeper.server.quorum.FollowerHandler.run(FollowerHandler.java:263) {code} So the followerhandler got an exception while writing to the socket but the follower was still waiting on the socket for a read and got a read timeout after 60 seconds or so. To just make sure we handle this rightly, we should close the socket at the followerhandler when we get an excpetion, so that the follower immediately recognizes that its disconnected from the leader. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
