Subject [jira] [Commented] (HBASE-16765) New SteppingRegionSplitPolicy, avoid too aggressive spread of regions for small tables.
Date Tue, 01 Nov 2016 20:22:58 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16765?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15626565#comment-15626565

Lars Hofhansl commented on HBASE-16765:
---------------------------------------

Pushed to 0.98, 1.1, 1.2, 1.3, 1.4, and 2.0 (during which I accidentally wiped history for
0.98, 1.4, and 1.1 and got heart-attach :) )

Now making it the default in 2.0.

> We just did some experiments on some larger clusters and found that while using IncreasingToUpperBoundRegionSplitPolicy
generally works well and is very convenient, it does tend to produce too many regions.
> Since the logic is - by design - local, checking the number of regions of the table in
question on the local server only, we end with more regions then necessary.
