Description

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'.
