[jira] [Updated] (DRILL-1590) Invalid result returned for queries
that has count with limit
[ https://issues.apache.org/jira/browse/DRILL-1590?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Hanifi Gunes updated DRILL-1590:
--------------------------------
Description:
The following query
{code:sql}
select count(*) from dfs.`local`.`yelp_academic_dataset_business.json` limit 1
{code}
returns
{panel}
844
{panel}
And this one down here
{code:sql}
select count(*) from dfs.`local`.`yelp_academic_dataset_business.json` limit 2
{code}
returns
{panel}
838
844
844
{panel}
Initial impression is that limit seems to work on batches rather than individual records.
ps: I had to test this on a detached head. We need to verify this on master
