gaojinchao reassigned HBASE-3521: --------------------------------- Assignee: gaojinchao > region be merged with others automatically when all data in the region has > expired and removed, or region gets too small. > ------------------------------------------------------------------------------------------------------------------------- > > Key: HBASE-3521 > URL: https://issues.apache.org/jira/browse/HBASE-3521 > Project: HBase > Issue Type: Improvement > Components: master, regionserver, scripts > Affects Versions: 0.90.0 > Reporter: zhoushuaifeng > Assignee: gaojinchao > Priority: Minor > > We have test a cluster which have more than 30,000 regions, max size of a > region is 512MB. At this situation, data no more growing, but remove some old > data and insert new, and regions will be more and more. And some regions may > be very small or empty. This occupies too much heapsize, and will be more if > regions cannot be merged. This will limit hbase running for a long time. > A script that does a survey to remove empty regions, or pick out adjacent > small regions that then does the online merge up seems like it would be > useful. -- This message is automatically generated by JIRA.
