-----------------------------------

             Summary: Basic Stats are not collected when running INSERT INTO commands on s3a
                 Key: HIVE-15396
                 URL: https://issues.apache.org/jira/browse/HIVE-15396
             Project: Hive
          Issue Type: Bug
          Components: Hive
            Reporter: Sahil Takiar
            Assignee: Sahil Takiar


{{numRows}} is not collected when running {{INSERT ... INTO ...}} commands against tables backed by S3 (and maybe even other blobstores).

The {{COLUMN_STATS_ACCURATE={"BASIC_STATS":"true"}}} entry is missing from the {{describe extended}} output.

Repro steps:

{code}
hive> drop table s3_table;
OK
Time taken: 1.87 seconds
hive> create table s3_table (col int) location 's3a://[bucket-name]/stats-test/';
OK
Time taken: 3.069 seconds
hive> insert into s3_table values (1), (2), (3);
