Summary: Switch back to get_table in HMS client for Hive 2.3.x (was:
Switch back to get_table in HMS client)
> Switch back to get_table in HMS client for Hive 2.3.x
> -----------------------------------------------------
>
> Key: HIVE-24608
> URL: https://issues.apache.org/jira/browse/HIVE-24608
> Project: Hive
> Issue Type: Bug
> Components: Metastore
> Affects Versions: 2.3.7
> Reporter: Chao Sun
> Priority: Major
>
> HIVE-15062 introduced a backward-incompatible change by replacing
> {{get_table}} with {{get_table_req}}. As consequence, when HMS client w/
> version > 2.3 talks to a HMS w/ version < 2.3, it will get error similar to
> the following:
> {code}
> AnalysisException: org.apache.hadoop.hive.ql.metadata.HiveException: Unable
> to fetch table testpartitiondata. Invalid method name: 'get_table_req';
> {code}
> Looking at HIVE-15062, the {{get_table_req}} is to introduce client-side
> check for capabilities. However in branch-2.3 the check is a no-op since
> there is no capability yet (it is assigned to null). Therefore, this JIRA
> proposes to switch back to {{get_table}} in branch-2.3 to fix the
> compatibility issue.
