It is the full region name - something like this: TestTable,0000262335,1300510101703.372a66d40705a4f2338b0219767602d3.
If you go to the master web UI and click on the table name and you will see all the regions for that table. It is the string under Table Regions / Name column. The other thing is: this operation is async. So, the split command will return almost immediately and the split operation is done async ... so, it may not reflect on your screen immediately. I suspect that your "asdf" string showing split regions is just a previous correct split operation succeeding asynchronously (i.e. cause & effect confusion ...) --Suraj On Tue, Mar 22, 2011 at 3:37 PM, Vivek Krishna <[email protected]> wrote: > When I entered the row key, it did nothing.
