    [ https://issues.apache.org/jira/browse/HIVE-17321?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16128375#comment-16128375

liyunzhang_intel commented on HIVE-17321:
-----------------------------------------

[~lirui]: understand, but i am very curious why the raw data size of orc table  is zero? 
When executing "INSERT OVERWRITE TABLE xxx SELECT * xxx",hive with orc will update statistics
from orc footer in [FileSinkOperator#closeOp|https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/exec/FileSinkOperator.java#L1081]
