-------------------------------
Summary: Table/Database Name Validation in SessionCatalog
Key: SPARK-14857
URL: https://issues.apache.org/jira/browse/SPARK-14857
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.0.0
Reporter: Xiao Li
We need validate the database/table names before storing these information in
`ExternalCatalog`.
For example, if users use `backstick` to quote the table/database names
containing illegal characters, these names are allowed by Spark Parser, but
Hive metastore does not allow them. We need to catch them in SessionCatalog and
issue an appropriate error message.
```
CREATE TABLE `tab:1` ...
```
This PR enforces the name rules of Spark SQL for `table`/`database`/`view`:
`only can contain alphanumeric and underscore characters.` Different from Hive,
we allow the names with starting underscore characters.
The validation of function/column names will be done in a separate JIRA.
