[jira] [Updated] (HIVE-4898) make vectorized math functions work end-to-end (update VectorizationContext.java)

     [ https://issues.apache.org/jira/browse/HIVE-4898?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Eric Hanson updated HIVE-4898:
------------------------------

    Status: Patch Available  (was: In Progress)

This patch is based off trunk (since vectorization has merged to trunk).

Enabled math functions to work end to end in SQL queries in vectorized mode. See the list of math functions affected in HIVE-4822. One function (unhex()) was removed because it has been changed to return BINARY, and binary is not yet supported with vectorization.

Ad hoc testing was performed for all the math functions to verify they  work from SQL queries.

> The vectorized math function VectorExpression classes were added in HIVE-4822. This JIRA is to allow those to actually be used in a SQL query end-to-end. This requires updating VectorizationContext to use the new classes in vectorized expression creation.
