> Workaround hive table name validation issue
> -------------------------------------------
>
> Key: SPARK-41355
> URL: https://issues.apache.org/jira/browse/SPARK-41355
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.4.0
> Reporter: Wan Kun
> Priority: Minor
>
> For example:
> * We want to create a table called {{tAb_I}}
> * Hive metastore will check if the table name is valid by
> {{MetaStoreUtils.validateName(tbl.getTableName())}}
> * Hive will call {{HiveStringUtils.normalizeIdentifier(tbl.getTableName())}}
> and then save the save the table name to lower case, *but after setting the
> local to "tr", it will be {{tab_ı}} which is not a valid table name*
> * When we run alter table command, we will first get the hive table from
> hive metastore which is not a valid table name.
> * Update some properties or other, and then try to save it to hive metastore.
> * Hive metastore will check if the table name is valid and then throw
> exception {{org.apache.hadoop.hive.ql.metadata.HiveException: [tab_ı]: is not
> a valid table name}}
