Tom White commented on HADOOP-6723: ----------------------------------- +1 > 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 > > Attachments: hadoop-6723.txt > > > 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.
