Attachment: ProposaltoimprovelogsplittingprocessregardingtoHBASE-7006.pdf
Hey,
I've came up a proposal to improve current log splitting process. Feedbacks are
welcome!
I temporarily assign the JIRA to me so that I can implement the proposal once
it gets green light.
Thanks,
-Jeffrey

> Just saw interesting issue where a cluster went down hard and 30 nodes had
> 1700 WALs to replay. Replay took almost an hour. It looks like it could run
> faster that much of the time is spent zk'ing and nn'ing.
> Putting in 0.96 so it gets a look at least. Can always punt.
