No, if region was moved, split or merged during snapshot operation - snapshot will fail. This is why taking snapshots on a large table is a 50/50 game. Disabling balancer,region merging and split before snapshot should help. This works in 2.0 Not sure if merge/split switch is available in 1.4 -Vlad On Tue, Mar 20, 2018 at 8:00 PM, Saad Mufti <[email protected]> wrote: > Hi, > > We are using HBase 1.4.0 on AWS EMR based Hbase.
