stack updated HBASE-5792:
-------------------------
Attachment: verify.txt
verify.txt
Matteo's patch only I moved the tool down under the wal package. Also added a
verify step that will look at resultant WAL and verify we are writing in
sequence. Oh, I also made the tool actually write a log (Was using default
constructor on region which won't create a log -- have to create the log
external and pass it in)
