Qiang Tian commented on HBASE-11096:
------------------------------------
Thanks Ted's comment. sure, will remove it.
Hi [~apurtell], [[email protected]], [~jxiang],
Regarding HBASE-11146, after studying HBASE-10569 and the code, it is by
design.
my concern is that, although master is also a regionserver, but from user's
perspective master is still of a 'master role', so if they deploy master
coprocessor and regionserver coprocessor on master and regionserver
respectively, they might not want to see 2 coprocessors created on master, in
which case the master coprocessor and regionserver coprocessor might have
potential conflict. --I just see we remove the master infoserver, and redirect
the request to regionserver infoserver in 0.99. maybe we could follow similar
way? i.e. disable RegionServerCoprocessorHost on master.
Could you please let me know your thoughts?
Thanks!
