Subject Hadoop Backup and Archival Cluster
Date Wed, 10 Feb 2016 18:15:45 GMT
Hi Friends,

I am planning to setup a Hadoop Cluster (A) with Cluster replication (B).
so that once data is reached to Cluster A it will replicated to Cluster D.
I am having one question if i delete data from Cluster A on the basis of
Time like one month old data is it also removed from Cluster B. if yes how
i can avoid this.

What i want to achieve.

1. Once data is reached to Cluster A it will automatically replicated to
Cluster B.

2. After one year old data from Cluster A remove automatically but not from
Cluster B.

3. If any one wants to run query on latest data Cluster A is available but
for Older data Cluster B is available.
