Andrew Purtell commented on HBASE-3270:
---------------------------------------

Attached patch that applies to 0.98+. Tested with master, some unit tests fail for other reasons. Tested with 0.98, all unit tests pass, minicluster will come up. No reason to think the change presents a problem. Ping [~stack]

> Todd suggests over in HBASE-3258 that writing hbase.version, we should write it off in a /tmp location and then move it into place after writing it to protect against case where file writer crashes between creation and write.
