Srikanth Srungarapu commented on HBASE-13008:
---------------------------------------------
In the configuration guidelines, we're
[recommending|http://hbase.apache.org/book.html#ops.capacity.regions] 20-200
regions. So, 1000 seems to be a very sensible upper limit. Will post a patch
soon.
> Better default for hbase.regionserver.regionSplitLimit parameter.

> Reporter: Srikanth Srungarapu
> Assignee: Srikanth Srungarapu
> Priority: Minor
>
> Currently, the default value for hbase.regionserver.regionSplitLimit is
> 2147483647. Couple of customers ran into trouble, as they ended up with too
> many regions(~7k) running on their region servers. Would it be possible for
> us to come up with better default or at least some new guard rail, which can
> be used for logging warnings when the number of regions are going overboard?
