> When hive.stats.collect.rawdatasize=true, 'rawDataSize' for an ORC table will
> result in value '0' after running 'analyze table TABLE_NAME compute
> statistics;'
> Reproduce step:
> (1) set hive.stats.collect.rawdatasize=true；
> (2) Generate an ORC table in hive, and the value of its 'rawDataSize' is NOT
> zero.
> You can find the value of 'rawDataSize' (NOT zero) by executing 'describe
> extended TABLE_NAME;'
> (4) Execute 'analyze table TABLE_NAME compute statistics;'
> (5) Execute 'describe extended TABLE_NAME;' again, and you will find that
> the value of 'rawDataSize' will be changed to '0'.
