Subject [jira] [Created] (HBASE-13008) Better default for hbase.regionserver.regionSplitLimit parameter.
Date Tue, 10 Feb 2015 23:43:11 GMT
Srikanth Srungarapu created HBASE-13008:
-------------------------------------------

             Summary: Better default for hbase.regionserver.regionSplitLimit parameter.
                 Key: HBASE-13008
                 URL: https://issues.apache.org/jira/browse/HBASE-13008
             Project: HBase
          Issue Type: Improvement
            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?
