[jira] [Updated] (PIG-2454) Make use of primitive tuples in builtin UDFs and operators

     [ https://issues.apache.org/jira/browse/PIG-2454?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Dmitriy V. Ryaboy updated PIG-2454:
-----------------------------------

    Attachment: PIG-2454.patch

This patch converts a number of internal UDFs and Physical Operators to use primitive tuples.

It also adds a couple of minor optimizations that address inefficiencies that popped up in my profiling -- excessive use of progress reporting, using tuple.append instead of tuple.set when we could pre-allocated the right number of fields, memoizing array.size() results (yes, that popped up in the profiler), etc.
