Subject [jira] [Updated] (HBASE-5101) Add a max number of regions per regionserver limit
Date Thu, 29 Dec 2011 00:41:35 GMT

]

Jonathan Hsieh updated HBASE-5101:
----------------------------------

    Description: In a testing environment, a cluster got to a state with more than 1500 regions
per region server, and essentially became stuck and unavailable.  We could add a limit to
the number of regions that a region server can serve to prevent this from happening.  This
looks like it could be implemented in the core or as a coprocessor.  (was: In a testing environment,
a cluster got to a state with more than 1500 regions per region server, and essentially because
stuck and unavailable.  We could add a limit to the number of regions that a region server
can serve to prevent this from happening.  This looks like it could be implemented in the
core or as a coprocessor.)
