unchecked exceptions thrown in IPC Connection orphan clients ------------------------------------------------------------
Key: HADOOP-6723 URL: https://issues.apache.org/jira/browse/HADOOP-6723 Project: Hadoop Common Issue Type: Bug Components: ipc Affects Versions: 0.20.2 Reporter: Todd Lipcon Assignee: Todd Lipcon Priority: Critical Fix For: 0.21.0, 0.22.0 If the server sends back some malformed data, for example, receiveResponse() can end up with an incorrect call ID. Then, when it tries to find it in the calls map, it will end up with null and throw NPE in receiveResponse. This isn't caught anywhere, so the original IPC client ends up hanging forever instead of catching an exception. Another example is if the writable implementation itself throws an unchecked exception or OOME. We should catch Throwable in Connection.run() and shut down the connection if we catch one. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
