> 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=trueï¼›
> (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'.
