Ashish Singhi commented on HBASE-14154:
---------------------------------------
Added a new configuration property {{DFS_REPLICATION}} for column family
descriptor.
Tested on one node cluster (RF set 1)
1. With default deplication
2. Create a table with one family with DFS_REPLICATION is set to 3, saw two
missing replicas for it in HDFS fsck report
3. Create a table with one family with DFS_REPLICATION is set to 3 and the
other with default replication, again saw two new missing replicas for it in
HDFS fsck report for the family with RF set to 3.
4. Create table with DFS_REPLICATION <= 0, it fails
Please review.
> DFS Replication should be configurable at column family level

> For eg: For a test table user would like to have only one copy instead of
> three(default).
