stack commented on HBASE-6659:
------------------------------
Again, sorry w/ my late review. Thanks for reverting the patch for now.
Yeah, seems odd adding currentsequenceid to RegionLoad? Its not part of region
load, I don't think. Its more a region attribute (this would not be the first
parameter that cannot be properly called a 'load').
High-level, we'd been trying to shrink the heartbeat with the hope that one day
it'd be so small we could drown it in a bathtub. Maybe thats not possible.
Outstanding is the fat serverload object updating the master on each heartbeat.
I don't have specific issues to hand but we've talked about making it so this
serverload could be obtained say via metrics/jmx since we are publishing the
bulk of it there as well as over here up on the heartbeat; seems silly
duplicating info. ServerLoad updating the master can be a bit lossy... same
with this new sequenceid attribute. We could put it on the heartbeat -- either
as is where serverload is a dumping ground of all we want to pass from
regionserver to master or we could put it in a data structure apart from
serverload -- and then maybe later do refactor of heartbeat to get its info
elsewhere (from zk if unchanging post regionserver registration) and out of
metrics w/ master pulling the info when its interested in particular?
