["Yongjun Zhang (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HADOOP-10543?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Yongjun Zhang updated HADOOP-10543:
-----------------------------------

    Description: 
If the cause of a RemoteException is PathIOException, RemoteException's unwrapRemoteException methods would fail, because some PathIOException constructors initialize 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} 


  was:
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}
