如何从 hive 或 impala 读取 Hbase 当前和以前版本的数据？

Question

I want to read Hbase current and previous versions of data from either hive or Impala.In my initial research, I found out that only current version can be accessed from Hive. So, currently is there any way to retrieve the older versions from either hive or Impala?

Answer 1

In case of Hive : Please see this

Seems like it's not possible to get different versions of same cell in Hive(even though Hbase has multiple versions of the same cell ) which always return the cell with latest timestamp. I believe we can handle this in tactical way. we can append the previous version to Hbase row key or else as separate cell (name, value)
In case of Impala : Please see limitations section
