-------------------------------
Summary: 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
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}}
