Marquis Wang updated HIVE-1803:
-------------------------------
Attachment: HIVE-1803.14.patch
HIVE-1803.14.patch
The issue with the last patch was the order in which
VirtualColumn.getRegistry().iterator() was returning. The old code stored the
virtual column registry as a HashMap, so I added the columns to the registry in
the order the HashMap would have returned them.
This patch fixes that. I'm still seeing errors in groupby1.q through
groupby6.q. It looks like various numbers are returning wrong, but it doesn't
appear to be related to the virtual columns. I can't really tell whether there
is a pattern to it.
can you take a look?
