luoyuxia commented on FLINK-27604:
----------------------------------
[[email protected]] Thanks for reporting it. Currently, it's not supported
to hbase data via Hive in Flink. But I think it's a valid requirement.
> flink sql read hive on hbase throw NPE

> Key: FLINK-27604
> URL: https://issues.apache.org/jira/browse/FLINK-27604
> Project: Flink
> Issue Type: Bug
> Components: Connectors / Hive
> Affects Versions: 1.13.6
> Reporter: zhangsan
> Priority: Major
>
> I have some table data on hbase, I usually read the hbase data by loading
> external tables through hive, I want to read the data through flink sql by
> reading hive tables, when I try with sql-client I get an error. I don't know
> if there is any way to solve this problem, but I can read the data using the
> spark engine.
