Subject Table Statistics In Hive
Date Mon, 02 Apr 2012 15:50:15 GMT
I've tried to collect statistics on an existing table in hive using the commands mentioned
in this wiki page - https://cwiki.apache.org/confluence/display/Hive/StatsDev
ANALYZE TABLE [TABLENAME] PARTITION(parcol1=..., partcol2=....) COMPUTE STATISTICS
But when I do a DESCRIBE EXTENDED [TABLENAME] after the stats collection has been completed,
I see the number of rows is still 0. Is there anything I am missing here? I am using Hive
0.7.1
Thanks
Anand
