Subject [jira] [Updated] (HIVE-5843) Transaction manager for Hive
Date Fri, 17 Jan 2014 04:12:30 GMT

     [ https://issues.apache.org/jira/browse/HIVE-5843?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Alan Gates updated HIVE-5843:
-----------------------------

    Attachment: HIVE-5843.3.patch

A new version of the patch.  It fixes the two failed unit tests noted by the buildbot, ties
up the loose ends in DDLTask, integrates the new DbTxnManager with the rest of the system,
and adds a number of new tests.  I've uploaded a source only version of the patch separately.

[~brocknoland], on the thrift method signatures I've changed them somewhat.  In the places
where they were taking more than one argument or returning values I've put in structs.  But
a number of the calls take a single long value, the transaction id.  I don't want to wrap
and unwrap this all the time, as I'd like this to be as fast as possible and it seems overkill.
 The odds that methods like abortTransaction() will take more than a transactionId seem low.
