We have hadoop cluster where default replication factor (dfs.replication)
is set to 1 ( this cluster is just plug and play, hence we don't need to
store more than 1 copies).

When we used drill *CTAS*, it has created table on *HDFS* with their
own *replication
factor of 3. *

*Questions are *-
1. why cant it uses Hadoop default replication factor ?
2. Is there any setting in Drill to change hadoop replication factor
realtime ?
