Is there a good writeup on what the settings that can be tweaked in hive as it pertains to writing parquet files are? For example, in some obscure pages I've found settings like parquet.compression, parquet.dictionary.page.size and parquet.enable.dictionary, but they were in reference to stock mapr reduce jobs, not hive, and thus, I don't even know what the defaults for these are when using hive. I tried doing hive -e "set"|grep "parquet\." but these settings aren't there.
Any documentation on what these are, what hive uses as defaults etc, and how I can optimize my parquet writing with hive would be appreciated.
