Subject [jira] [Commented] (HIVE-15717) Class "org.apache.hive.beeline.Rows.Row" constructor is CPU consuming due to exception handling
Date Wed, 25 Jan 2017 23:27:26 GMT

    [ https://issues.apache.org/jira/browse/HIVE-15717?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15838798#comment-15838798

Thejas M Nair commented on HIVE-15717:
--------------------------------------

[~taoli-hwx] Returning false looks appropriate in this case.
We don't support delete/insert/update in HiveBaseResultSet.

A possible future optimization for beeline would be to recognize 'SQLFeatureNotSupportedException'
 exception and not make further calls to it. Created a related jira around use of 'SQLFeatureNotSupportedException'
 - HIVE-15730

> The exception handling from the 3 methods calls (rowDeleted, rowInserted and rowUpdated).
The implementation of these methods in org.apache.hive.jdbc.HiveBaseResultSet class is just
throwing SQLException("Method not supported”), i.e. no real implementations.
