-------------------------------------------
> Show abbreviated row counts in DESCRIBE output
> ----------------------------------------------
>
> Key: IMPALA-8181
> URL: https://issues.apache.org/jira/browse/IMPALA-8181
> Project: IMPALA
> Issue Type: Improvement
> Components: Frontend
> Affects Versions: Impala 3.1.0
> Reporter: Paul Rogers
> Assignee: Paul Rogers
> Priority: Minor
>
> A recent change added plan node cardinality to the DESCRIBE output using a
> "metric" format: 123.46M instead of 123456789. This makes the output easier
> to read. Also, since all numbers are estimate, having seven or eight digits
> of precision is not very helpful.
> This ticket requests that the same formatting be used for the other places
> where the DESCRIBE output shows row counts: table stats, extrapolated row
> count, partition row counts, and so on.
