Pengcheng Xiong commented on HIVE-14143: ---------------------------------------- [~nemon], thanks a lot for your explanation. I think current assumption that "empty column ids means read all columns" is confusing and misleading. I would prefer the following assumption: {code} getNeededColumnIDs==null or empty ===means==> do not need any columns {code} If you agree, could you please change the code accordingly? Thanks. > RawDataSize of RCFile is zero after analyze > -------------------------------------------- > > Key: HIVE-14143 > URL: https://issues.apache.org/jira/browse/HIVE-14143 > Project: Hive > Issue Type: Bug > Components: Statistics > Affects Versions: 1.2.1, 2.1.0 > Reporter: Nemon Lou > Assignee: Nemon Lou > Priority: Minor > Attachments: HIVE-14143.patch > > > After running the following analyze command ,rawDataSize becomes zero for > rcfile tables. > {noformat} > analyze table RCFILE_TABLE compute statistics ; > {noformat} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
