Re: Migrate data from one cluster to another cluster

Hi @xBigDatax,

 

 

What data are we talking about here? HDFS, Hive, HBase, Impala, Search etc? I assume you are not using Cloudera Manager?

 

Thanks,

Li

Re: Migrate data from one cluster to another cluster

Hi @xBigDatax,

 

You can take a look at BDR feature (which should handle HDFS, Hive, Impala) since you are using Cloudera Manager:

For search, you can take a look at this blog:

and public doc:

https://www.cloudera.com/documentation/enterprise/6/latest/topics/search_backup_restore.html

 

For HBase, you can take a look at this:

You can also explore the distcp tool which is a general utility for copying large data sets between distributed filesystems within and across clusters.

Thanks and hope this helps,
