Jing Zhao updated HDFS-2434:
----------------------------
Attachment: HDFS-2434.trunk.003.patch
Made some further changes for the patch. In the testCorrupt testcase, because
currently the delete operation will not remove the pending record in NN, it is
possible that before the DN sends back a "block has been received" msg to NN,
the block has been deleted due to the deletion request. In that case, it seems
that the pending record cannot be removed until timeout.
Thus the new patch first waits for the recovery to finish, and then do the
deletion.
