stack updated HBASE-10201:
--------------------------
Resolution: Fixed
Fix Version/s: (was: 1.0.0)
Release Note: Adds new flushing policy mechanism. Default,
org.apache.hadoop.hbase.regionserver.FlushLargeStoresPolicy, will try to avoid
flushing out the small column families in a region, those whose memstores are <
hbase.hregion.percolumnfamilyflush.size.lower.bound. To restore the old
behavior of flushes writing out all column families, set
hbase.regionserver.flush.policy to
org.apache.hadoop.hbase.regionserver.FlushAllStoresPolicy either in
hbase-default.xml or on a per-table basis by setting the policy to use with
HTableDescriptor.getFlushPolicyClassName().
Hadoop Flags: Reviewed
Status: Resolved (was: Patch Available)
Pushed to master branch
> Port 'Make flush decisions per column family' to trunk

> Currently the flush decision is made using the aggregate size of all column
> families. When large and small column families co-exist, this causes many
> small flushes of the smaller CF. We need to make per-CF flush decisions.
