Lefty Leverenz commented on HIVE-5728:
--------------------------------------
Why do the comment & description for *hive.exec.orc.default.row.index.stride*
still say "stripe" instead of "stride"? "Define the default ORC index stripe
in bytes." -- perhaps "index stripe" is the same as "stride" but that's too
easy to confuse with the other meaning of stripe.
And is it really defined in bytes, not number of rows? The default of 10000
seems more appropriate for rows.
In the meantime I've found HIVE-5091 which explains block padding, so I can add
a link to it when I put *hive.exec.orc.default.block.padding* in the wiki.
Someday we might include that kind of information in hive-default.xml.template
but not today.
