Is it possible to restrict/provide access in HBase based on value/data in particular column ?
for eg. if data in column 'colgrp' = 'group1', provide access (to the row) to users belonging to 'group1'.
similarly, if data in column 'colgrp' = 'group2', provide access (to the row) to users belonging to 'group1'
is there a way to achieve this in Hbase (or OpenTSDB) ?
Pls. let me know.
Internal to HBase, no. I am not aware of such a feature.
You can try to use cell-level ACLs or the visibility labels feature to implement the same type of control.
