Hi team,
I created a table through HBase api, and then created a view for it on Phoenix.
And for some reasons, i dropped the view, but coprocessors are still attached
on this table.
>From hbase webui:
'recommend:vulgar_feed', {TABLE_ATTRIBUTES => {coprocessor$1 =>
'|org.apache.phoenix.coprocessor.ScanRegionObserver|805306366|', coprocessor$2
=>
'|org.apache.phoenix.coprocessor.UngroupedAggregateRegionObserver|805306366|',
coprocessor$3 =>
'|org.apache.phoenix.coprocessor.GroupedAggregateRegionObserver|805306366|',
coprocessor$4 =>
'|org.apache.phoenix.coprocessor.ServerCachingEndpointImpl|805306366|'}, {NAME
=> 'b'}

My question is, is it possible to drop those coprocessors through like phoenix
admin, or some tools i missed? Although no harm done, i just think this drop
not clean enough...
