    Description

      The edit log generated by hdfs ec -unsetPolicy generates an OP_REMOVE_XATTR entry in edit logs, but the payload like xattr namespace / name / vaue are missing:

        <RECORD>
          <OPCODE>OP_REMOVE_XATTR</OPCODE>
          <DATA>
            <TXID>420481</TXID>
            <SRC>/</SRC>
            <RPC_CLIENTID>b098e758-9d7f-48b7-aa91-80ca52133b09</RPC_CLIENTID>
            <RPC_CALLID>0</RPC_CALLID>
          </DATA>
        </RECORD>
      

      As a result, when Active NN restarts, or the Standby NN replay edits, this op has not effect.
