Scanner spins when there are concurrent inserts to column family
----------------------------------------------------------------
Key: HBASE-1206
URL: https://issues.apache.org/jira/browse/HBASE-1206
Project: Hadoop HBase
Issue Type: Bug
Affects Versions: 0.19.0
Reporter: Ben Maurer
Fix For: 0.19.1

of the irrelevent inserts many times as flushes occurred.
However, if I put the column that I was outputting to in the list of columns to
scan for, everything worked quickly.
The code that's causing this is:
