      Description

      InvestigatingĀ HBASE-19893, I'm encountering another issue.

      Steps to reproduce are as follows:

      1. Create a table

      create "test", "cf", {REGION_REPLICATION => 2}

      2. Load data to the table

      (0...2000).each{|i| put "test", "row#{i}", "cf:col", "val"}

      3. Split the table

      split "test"

      4. Take a snapshot for the table

      snapshot "test", "snap"

      And I encountered the following error:

      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=[] done=[] }
