> Key: DRILL-1513
> URL: https://issues.apache.org/jira/browse/DRILL-1513
> Project: Apache Drill
> Issue Type: Bug
> Components: Client - CLI
> Affects Versions: 0.5.0
> Reporter: MUFEED USMAN
> Assignee: Ramana Inukonda Nagaraj
>
> While querying a data (sample below):
> [root@n69 ~]# head webdata.tbl
> 1.1.11.1.1234567890123456|user123|www.abcd.com/en/US/abcde/|www.abcd.com/en/US/abcde/|2014-01-09|pg|meta.handheldfriendly|true|4
> on a 3-node running Drill 0.5.0
> select columns[0], count(*) as CNT from dfs.`/user/webdata.tbl` group by
> columns[0] order by CNT desc limit 10;
> And the query console shows no signs of breakage (that from an end-user
> perspective is bad).
> Only a kill <sqlline PID> gets me out of the unresponsive sqlline console.
> Whereas a simple count(*) on the same data works just fine.
> 0: jdbc:drill:zk=n69:5181,n72:5181,n73:5181> select count(*) from
> dfs.`/user/webdata.tbl`;
