Lars Hofhansl commented on HBASE-12031:
---------------------------------------
[~vrodionov], can you install the HBase formatter (if you use Eclipse)? It's in
dev-support. It's a bit hard to make out the changes among all the whitespace
changes.
Also in order to commit it, it needs to be formatted right :)
(I'll locally apply and then diff it with ignoring whitespace to look at it for
now)

> This JIRA to improve performance of multiple scanners running on a same
> region in parallel. The scenarios where we will get the performance benefits:
> * New TableInputFormat with input splits smaller than HBase Region.
> * Scanning during compaction (Compaction scanner and application scanner over
> the same Region).
