Coprocessor hooks can be called in the respective handlers
----------------------------------------------------------
Key: HBASE-5584
URL: https://issues.apache.org/jira/browse/HBASE-5584
Project: HBase
Issue Type: Improvement
Reporter: ramkrishna.s.vasudevan
Assignee: ramkrishna.s.vasudevan
Fix For: 0.96.0
Following points can be changed w.r.t to coprocessors
-> Call preCreate, postCreate, preEnable, postEnable, etc. in their respective
handlers
-> Currently it is called in the HMaster thus making the postApis async w.r.t
the handlers
-> Similar is the case with the balancer.
with current behaviour once we are in the postEnable(for eg) we any way need to
wait for the main enable handler to
be completed.
We should ensure that we dont wait in the main thread so again we need to spawn
a thread and wait on that.
On the other hand if the pre and post api is called on the handlers then only
that handler thread will be
used in the pre/post apis
If the above said plan is ok i can prepare a patch for all such related changes.
