Prasanth J updated HIVE-6300:
-----------------------------
Attachment: HIVE-6300.2.patch
[~leftylev] Thanks for pointing out the nitty-gritty mistakes. That was really
usefull. I removed the hive config hive.stats.avg.row.size as it is no longer
required. Average row size will be computed from data size and schema in very
stages of operator tree (TableScanOperator), so it should be available to all
operators (including LIMIT). Can you please skim through it again to see if it
looks good?
> Add documentation for stats configs to hive-default.xml.template
