[ https://issues.apache.org/jira/browse/DRILL-5278?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15900958#comment-15900958 ]
Khurram Faraaz commented on DRILL-5278:
---------------------------------------
This is by design, and works as expected.
> CTTAS store.format=csv, returns one extra record
> ------------------------------------------------
>
> Key: DRILL-5278
> URL: https://issues.apache.org/jira/browse/DRILL-5278
> Project: Apache Drill
> Issue Type: Bug
> Components: Storage - Text & CSV
> Affects Versions: 1.10.0
> Reporter: Khurram Faraaz
>
> When store.format = csv, we see incorrect results returned, an extra record is returned, as compared to when store.format = parquet. The difference is seen when doing a count over a temporary table created in Drill.
> Drill 1.10.0 git commit ID : 300e9349
> Steps to reproduce the problem.
