Subject [jira] Updated: (HIVE-1117) Make QueryPlan serializable
Date Fri, 29 Jan 2010 07:27:34 GMT

     [ https://issues.apache.org/jira/browse/HIVE-1117?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Zheng Shao updated HIVE-1117:
-----------------------------

    Attachment: HIVE-1119.1.patch

This patch makes all tasks and works serializable.

Currently there are no additional tests.
Once the whole QueryPlan is serializable, we will serialize the whole query plan after compilation
and deserialize the whole plan before execution. This will automatically test all the serialization/deserialization.

I prefer to commit this one first given that major code refactoring/clean-up is happening.
