Yongjun Zhang created HADOOP-10543:
--------------------------------------

             Summary: RemoteException's unwrapRemoteException method failed for \
PathIOException  Key: HADOOP-10543
                 URL: https://issues.apache.org/jira/browse/HADOOP-10543
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 2.4.0
            Reporter: Yongjun Zhang
            Assignee: Yongjun Zhang


If the cause of a RemoteException is PathIOException, RemoteException's \
unwrapRemoteException methods would fail, because PathIOException overwrites the \
cause to null, which makes Throwable to throw exception at {code}
    public synchronized Throwable initCause(Throwable cause) {
        if (this.cause != this)
            throw new IllegalStateException("Can't overwrite cause");
{code}
