-------------------------------------------
> ... how can I rebuild for this patch? I can’t log in Jenkins WebUI.
I mean I already have started another Jenkins build for the patch. For
rebuilding, you may click "Cancel Patch" and then "Submit Patch". It will
trigger a new build.

> When (BlockOpResponseProto#getStatus() != SUCCESS), it helps with debugging
> if DFSClient can add BlockOpResponseProto's message to the exception message
> applications will get. For example, instead of
> {noformat}
> throw new IOException("Got error for OP_READ_BLOCK, self="
> + peer.getLocalAddressString() + ", remote="
> + peer.getRemoteAddressString() + ", for file " + file
> + ", for pool " + block.getBlockPoolId() + " block "
> + block.getBlockId() + "_" + block.getGenerationStamp());
> {noformat}
> It could be,
> {noformat}
> throw new IOException("Got error for OP_READ_BLOCK, self="
> + peer.getLocalAddressString() + ", remote="
> + peer.getRemoteAddressString() + ", for file " + file
> + ", for pool " + block.getBlockPoolId() + " block "
> + block.getBlockId() + "_" + block.getGenerationStamp()
> + ", status message " + status.getMessage());
> {noformat}
> We might want to check out all the references to BlockOpResponseProto in
> DFSClient.
