[jira] [Commented] (HIVE-21151) Fix support of dot in quted identifiers

["Zoltan Haindrich (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-21151?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16749616#comment-16749616 ] 

Zoltan Haindrich commented on HIVE-21151:
-----------------------------------------

I think the a solution candidate would be to introducing a TableRef object which would contain the catalog/database/table name infos...so that these half solutions could go away...

so instead of passing around "Strings" about {{dbName, tableName}}  ; a single TableRef could be passed; which could ensure that both the database/catalog name is present everywhere - and its the correct one; because it would only needed to be construct properly at some early stage.

> Dot should be allowed in quoted identifiers; but because there are some methods which rely on splitting the "dbtable" string by the dot HIVE-16907 have removed that option.
