Description

DFSClient should diff the writing files with namespaceId and iNodeId, because the writing files may belongs to different namespace with the same iNodeId.

And the related code as bellows:

public void putFileBeingWritten(final long inodeId,
      final DFSOutputStream out) {
    synchronized(filesBeingWritten) {
      filesBeingWritten.put(inodeId, out);
      // update the last lease renewal time only when there was no
      // writes. once there is one write stream open, the lease renewer
      // thread keeps it updated well with in anyone's expiration time.
      if (lastLeaseRenewal == 0) {
        updateLastLeaseRenewal();
      }
    }
  }
