---------------------------------------
Summary: analyze table compute stats for columns should collect
basic stats as well
Key: HIVE-14729
URL: https://issues.apache.org/jira/browse/HIVE-14729
Project: Hive
Issue Type: Improvement
Components: Statistics
Reporter: Ashutosh Chauhan
Currently user need to run following two statements to collect stats:
{code}
analyze table T compute statistics;
analyze table T compute statistics for columns;
{code}
Its little confusing for users that they need to collect both stats. Since
basic stats are cheap to compute, we should collect them even in case of column
stats, so that by running single statement users can get all stats. This leaves
with the possibility of fast basic stats collection with first statement which
will be good to have.
