Lefty Leverenz commented on HIVE-6300:
--------------------------------------
The patch missed describing *hive.stats.avg.row.size* in
hive-default.xml.template, so I used its HiveConf comment in the wiki:
{quote}
In the absence of table/partition statistics, average row size will be used to
estimate the number of rows/data size.
{quote}
Please review and revise as needed. Perhaps it's not clear enough that
"average row size" means the value of this parameter.
The other parameters covered in this jira are also in the wiki, before this one.
