Jean-Marc Spaggiari commented on HBASE-16765:
---------------------------------------------
Just come back from customer site last week... I was smiling when I saw all
tables configured with ConstantSizeRegionSplitPolicy... Cluster was about 300
HBase servers. They complained about HBase creating way to many regions for
small tables, so they just configured each table to use
ConstantSizeRegionSplitPolicy. So we should definitively do something on that
side...

>
> 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.
