> Investigating HBASE-19893, I'm encountering another issue.
> Steps to reproduce are as follows:
> 1. Create a table
> {code:java}
> create "test", "cf", {REGION_REPLICATION => 2}{code}
> 2. Load data to the table
> {code:java}
> (0...2000).each{|i| put "test", "row#{i}", "cf:col", "val"}{code}
> 3. Split the table
> {code:java}
> split "test"{code}
> 4. Take a snapshot for the table
> {code:java}
> snapshot "test", "snap"{code}
> And I encountered the following error:
> {code:java}
> hbase(main):004:0> snapshot "test", "snap"
> ERROR: org.apache.hadoop.hbase.snapshot.HBaseSnapshotException: Snapshot {
> ss=snap table=test type=FLUSH } had an error. Procedure snap { waiting=[]
