Matteo Bertozzi commented on HBASE-15071:
-----------------------------------------
the bypass() documentation says
{quote}Call to indicate that the current coprocessor's return value should be
used in place of the normal HBase obtained value.{quote}
so in my opinion bypass() make sense for stuff that return a value, like the
get/scanners.
bypassing an addColumn() or a createTable() probably does not make any sense.
is anyone doing its own create instead of an hbase create? how the new stuff
created/added by a non hbase will play with the rest of the system?
maybe we can just remove the bypass boolean for operation that do not make
sense.
> Cleanup bypass semantic in MasterCoprocessorHost

> Key: HBASE-15071
> URL: https://issues.apache.org/jira/browse/HBASE-15071
> Project: HBase
> Issue Type: Task
> Components: Coprocessors
> Affects Versions: 2.0.0
> Reporter: stack
> Priority: Blocker
>
> Lets decide on this one before we release 2.0.0.
> A bunch of methods in MasterCoprocessorHost on the 'pre' step allow returning
> true which indicates the method invocation is not to proceed.
> Not all 'pre' steps do this. Just some.
> Seems a little arbitrary.
> How we skip out if we are not proceed with the invocation is also a little
> arbitrary.
> When a deleteColumn call is supposed to skip out, it returns a -1, a
> non-procId. If we are to skip a balance call, we log that CP said skip and
> then return false to indicate the balancer did not run (why?). Elsewhere we
> just exit silently. In createNamespace we used to exit silently but
> HBASE-14888 just changed it so we throw a BypassCoprocessorException
> instead...
> Lets make them all work the same way.
> (This issue comes of chat w/ Matteo)
