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
table1,region1,start_key1,end_key1
table2,region1,start_key1,end_key1
table3,region1,start_key1,end_key1
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.
