Subject [jira] [Commented] (HBASE-4991) Provide capability to delete named region
Date Thu, 23 Feb 2012 02:33:48 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4991?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13214223#comment-13214223

Mubarak Seyed commented on HBASE-4991:

If we specify only start and end key, what happens if multiple regions (belongs to mutiple
tables) holds the same start/end key?

For example: I have 3 tables => table1, table2, table3
If i pre-split them using first two characters like [0-9][a-z]=> we get 36 x 36 = 1296
regions => 1296 x 3 = 3888 total regions (across all RSs), so key would look like

a0.... to az.....
z0... to zz...
01... to 0z...

so we end up


start_key1 and end_key1 needs to be resolved at input level unless fully qualified path of
_table1,region1,start_key1_ and _table1,region1,end_key1_ is specified.
