Lefty Leverenz commented on HIVE-11684:
---------------------------------------
Doc note: This adds three configuration parameters to HiveConf.java, so they
need to be documented in the wiki.
* hive.optimize.limitjointranspose
* hive.optimize.limitjointranspose.reductionpercentage
* hive.optimize.limitjointranspose.reductiontuples
Questions:
# In the description of *hive.optimize.limitjointranspose*, does
"hive.optimize.limitjointranspose.reduction" refer to both
*hive.optimize.limitjointranspose.reductionpercentage* and
*hive.optimize.limitjointranspose.reductionpercentage* or is there another
parameter named *hive.optimize.limitjointranspose*?
# Does "percentage" in *hive.optimize.limitjointranspose.reductionpercentage*
mean decimal fraction or does the default value of 1.0 really mean 1%?
