Aaron T. Myers updated HDFS-3926:
---------------------------------

    Attachment: regular-ha-doc.diff
                qjm-ha-doc.diff
                HDFS-3926.patch

Thanks a lot for the comments, Todd. Here's a patch which addresses all of them as you suggested,
except for the following:

bq. This paragraph no longer seems relevant.

Agree that part of it is now irrelevant with the QJM, but not the whole thing. I took out
the part of this paragraph that said the fencing was critical, but left in the part that describes
how to configure the fencing methods.

This patch also takes the liberty of correcting the value for the dfs.ha.fencing.ssh.connect-timeout
sample configuration, to no longer be malformed XML.
