[jira] Updated: (HIVE-453) external table metastore and execution codepaths use default FileSystem object instead of using one derived from the supplied path

["Joydeep Sen Sarma (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HIVE-453?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Joydeep Sen Sarma updated HIVE-453:
-----------------------------------

    Attachment: hive-453.patch.2

- add rollback of fs operations if transaction fails
- added a couple of negative tests that verify that metadata transactions don't succeed if fs operations fail.

also added a cli option (by default false)  to keep processing queries even if we hit errors. this was necessary for writing the negative tests and is likely useful more generally as well.
