["Jim Kellerman (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-748?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12636112#action_12636112 ] 

Jim Kellerman commented on HBASE-748:
-------------------------------------

Reviewed patch:

No javadoc for HConnection.getRegionServerForManyRows

Javadoc for HTable.getWriteBuffer, HRegionInterface.batchUpdate(final byte[] regionName, final BatchUpdate[] b), HRegion.batchUpdate(BatchUpdate[]), BatchUpdate.getSize are incomplete

Do HTable.flushCommits and HTable$ClientScanner.initialize need to be public? Can't they just be protected?

> HBASE-747 introduced a simple way to batch update many rows. The goal of this issue is to have an enhanced version that will send many rows in a single RPC to each region server. To do this, the client code will have to figure which rows goes to which server, group them accordingly and then send them.
