Mingjie Lai commented on HBASE-4554: ------------------------------------ @Ted. As we original proposed, we can add arbitrary content after coprocessor$. You suggested to only use (auto-generated) number after $. Either way should work. > Allow set/unset coprocessor table attributes from shell. > -------------------------------------------------------- > > Key: HBASE-4554 > URL: https://issues.apache.org/jira/browse/HBASE-4554 > Project: HBase > Issue Type: Improvement > Components: coprocessors > Reporter: Mingjie Lai > Assignee: Mingjie Lai > Fix For: 0.92.0 > > > Table/region level coprocessor -- RegionObserver -- can be configured by > setting a HTD's attribute which matches Coprocessor$*. > Current shell -- alter -- cannot support to set/unset a table's arbitrary > attribute.
