-------------------------------
Resolution: Not A Problem
> Make hive metastore convert config can be changed session level
> ----------------------------------------------------------------
>
> Key: SPARK-32818
> URL: https://issues.apache.org/jira/browse/SPARK-32818
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.1.0
> Reporter: angerszhu
> Priority: Major
>
> There are some cases that we have history hive table, in origin, it use
> textfile serde, later it's change to orc serde, since during convert, it
> will use table level serde to scan all partition, if some old partition file
> format is not same , will failed to convert , we need to close metastoer
> convert and restart spark program.
> It's bad for adhoc engine such as long running spark thrift server. so I
> think it's necessary to make these two config can be changed for use in
> session level
