HI All,
I need to load a secondary cluster with data from cluster1. The data is approx 1Tb in size. Are snapshots preferred over Export/Import?
Our clusters cannot talk to each other, and I wanted to do a test like the following:
bin/hbase class org.apache.hadoop.hbase.snapshot.tool.ExportSnapshot -snapshot MySnapshot -copy-to hdfs://cluster2:8020/hbase -mappers 16
I am guessing the data is streamed from one cluster to another. Do we need to push from a source master to a destination master ie. hdfs://masternode2:8020/hbase? Do all the destination masters need to have port 8020 open or do the data nodes need to be opened also?
Thanks in advance!
