Subject Re: Does Hbase backup process support encryption while transporting the data from one cluster to other cluster
Date Tue, 09 Oct 2018 14:54:44 GMT
Hi neo0731,
depending on what you mean by encryption, it can mean Hadoop at-rest
encryption, Hadoop data transport encryption, Hadoop RPC necryption, HBase
data transport encryption, Hbase RPC encryption, SSL encryption (Hadoop
WebHDFS, HBase Thrift)

distcp supports Hadoop at-rest encryption, and it supports Hadoop data
transport encryption/Hadoop RPC encryption. There's a proposal to support
webhdfs styled URL in distcp, and that way it will be able to support SSL
encrypted traffic.

HBase replication supports Hadoop at-rest encryption. We've seen the use
case in production.
I am aware of some bugs in HBase backup tool that can't read Hadoop
encryption zone files.
