stack commented on HBASE-4991:
------------------------------
bq. When we change the location of rename() call from master to region server
for distributed log splitting, the duration was shortened from 22 minutes to 7
minutes for the same dataset.
Because rename was done via multiple clients rather than in parallel on master?
You sure it wasn't because of something else? (Distributed splitting is a
different type of process to what is going on here)
What do you want to farm out to the regionservers? We are already farming out
work in the design above. We ask the regionservers to close regions for us.
You want to farm out more than this? Control? To what end other than
complicating the design?
bq. I wonder if you have statistics showing that master-side operation (for
moving/deleting data of old regions) makes no difference in performance w.r.t.
distributed operations.
Well, stands to reason I'd think. I'd put it on you to come up w/ proof that
what seems reasonable actually isn't, at least when talking about the tens of
regions at most which is what I think this issue is about.
