[jira] Commented: (HIVE-132) Show table and describe results should be read via FetchTask

["Ashish Thusoo (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-132?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12660770#action_12660770 ] 

Ashish Thusoo commented on HIVE-132:
------------------------------------

A few nitpicks:
1. Why did we get rid of : in the explain plan output "Table Information:" has been replaced by "Table Information" without a new line. Also there seems to be extra space/tab after the column metadata is printed.

Thanks for fixing dailed to failed :).. that has been there for so long... :))

For the general code:
1. In DDLSemanticAnalyzer.java in the function createFetchTask setSerializationNullFormat is "" - should this be a null string instead or a ""

Otherwise it looks good to me.

> Right now there is a different code path in the Driver for show tables/describe etc. By adding the FetchTask the code paths will be merged. In addition, the results of these statements will be readable via JDBC.
> Going forward, we should provide SQL access to our metastore similar to access provided by Oracle or mysql to their catalog tables. In this jira, I will just add schema information to show tables and describe queries.
