FAQ
Data replication in Impala is the same as it in Hadoop (HDFS) - at least
that's how I understand it. In short, it replicates the data based on the
hdfs.replication setting in the hdfs settings file. Here's a link to the
Hadoop architecture that may help with explaining that.

Can anyone explain whether there is data replication in impala? if yes
then how the data is replicated?
