Andrew Purtell commented on HBASE-7042:
---------------------------------------
Seems reasonable.
On the current patch:
- Can we use the same Exec and ExecResponse classes for both master and RS
endpoint invocations? (I.e. get rid of MasterExec and MasterExecResult?)
- The patch handles system coprocessors, those registered by Configuration, but
what about table coprocessors? Table coprocessors are loaded as dictated by
table attributes. Should the master load those when creating or updating table
schema and discovers that coprocessor load directives now exist in the schema?
We wouldn't need to load a table coprocessor into the master if the table is
disabled, but once the table is enabled, then we would?
