Subject [jira] [Commented] (PHOENIX-2216) Support single mapper pass to CSV bulk load table and indexes
Date Mon, 31 Aug 2015 20:09:45 GMT


Gabriel Reid commented on PHOENIX-2216:

I looked at this a while back, but never got far enough to actually get it going (due to lack
of time).

The idea behind HBASE-3727 is what is needed I think, but from my previous look at this I'm
pretty sure that it wouldn't be too difficult to get this working via the "normal" [Hadoop

Using [Crunch|] would make this trivial, but I think that that's probably
way too big of a dependency to pull in to do something like this.

I would _love_ to work on this, but I don't feel like I can put in enough time to get it done
right now -- of course I'd be happy to collaborate (at least in terms of reviewing/discussing),
but I don't think I can put together a working patch for this in the really short-term.

> Instead of running separate MR jobs for CSV bulk load: once for the table and then once
for each secondary index, generate both the data table HFiles and the index table(s) HFiles
in one mapper phase.
> Not sure if we need HBASE-3727 to be implemented for this or if we can do it with existing
HBase APIs.
