----------------------------

             Summary: Missing null check in RpcProgramNfs3#read(XDR, SecurityHandler)
                 Key: HDFS-6582
                 URL: https://issues.apache.org/jira/browse/HDFS-6582

          Issue Type: Bug
            Reporter: Ted Yu
            Priority: Minor


Around line 691:
{code}
        FSDataInputStream fis = clientCache.getDfsInputStream(userName,
            Nfs3Utils.getFileIdPath(handle));

        try {
          readCount = fis.read(offset, readbuffer, 0, count);
{code}
fis may be null, leading to NullPointerException
