Subject [jira] [Commented] (HBASE-3857) Change the HFile Format
Date Wed, 20 Jul 2011 04:22:58 GMT

stack commented on HBASE-3857:
------------------------------

@Mikhail I'll finish my skim through your quality patch this evening but meantime here are
a few things:

1. Mind if I run a vote up on dev on committing this to trunk?  (My sense is that some would
rather it go in after 0.92 branch is cut but I'm thinking it should be included in 0.92, our
next major release; its a radical change but the quality of the contribution, the tests included,
the careful consideration given to migrating in-place, and that you fellas have been running
this in house make me think it low risk pulling this in now.  It looks like Andrew agrees
with me).
2. Would you mind attaching the src document for your pdf design?  It looks like its word.
 My thinking is that we could use the openoffice saveas docbook to get a rough cut at a docbook
section on this new format that we could work over to include in our site documentation.

This stuff is excellent.
