Todd Lipcon commented on HADOOP-8397: ------------------------------------- I think we just need to check for a null result, and throw EOFException in that case. > NPE thrown when IPC layer gets an EOF reading a response > -------------------------------------------------------- > > Key: HADOOP-8397 > URL: https://issues.apache.org/jira/browse/HADOOP-8397 > Project: Hadoop Common > Issue Type: Bug > Components: ipc > Affects Versions: 2.0.0 > Reporter: Todd Lipcon > Priority: Critical > > When making a call on an IPC connection where the other end has shut down, I > see the following exception: > Caused by: java.lang.NullPointerException > at > org.apache.hadoop.ipc.Client$Connection.receiveResponse(Client.java:852) > at org.apache.hadoop.ipc.Client$Connection.run(Client.java:781) > from the lines: > {code} > RpcResponseHeaderProto response = > RpcResponseHeaderProto.parseDelimitedFrom(in); > int callId = response.getCallId(); > {code} > This is because parseDelimitedFrom() returns null in the case that the next > thing to be read on the stream is an EOF. -- This message is automatically generated by JIRA.
