----------------------------------------
[~mbertozzi] I made the change, but the ruby shell code seems won't accept this
line I added in admin.rb: java_import
org.apache.hadoop.hbase.protobuf.generated.HBaseProtos.SnapshotDescription
It throws error when I try to start hbase shell. Any idea?
[root@hbasetestnode-f7c52eba:/usr/lib/hbase/lib/ruby/hbase]# hbase shell
NoMethodError: undefined method `SnapshotDescription' for

> We are using snapshot feature to do HBase disaster recovery. We will do
> snapshot in our production cluster periodically. The current flush snapshot
> policy require all regions of the table to coordinate to prevent write and do
> flush at the same time. Since we use WALPlayer to complete the data that is
> not in the snapshot HFile, we don't need the snapshot to do coordinated
> flush. The snapshot just recored all the HFile that are already there.
> I added the parameter in the HBase shell. So people can choose to use the
> NoFlush snapshot when they need, like below. Otherwise, the default flush
> snpahot support is not impacted.
> >snaphot 'TestTable', 'TestSnapshot', 'skipFlush'
