Hi, all
We are running Hbase 0.18.1 over Hadoop 0.18.2 in a small cluster
(name node/master host + 3 data node/region server hosts). Recently,
we have run into org.apache.hadoop.hbase.DroppedSnapshotException
(see below).
Has anybody run into this?
Thank you for your cooperation,
M.
P. S. The exception details:
