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

             Summary: Single corrupt compressed json file (in s3) causes query failure
                 Key: DRILL-5944
                 URL: https://issues.apache.org/jira/browse/DRILL-5944
             Project: Apache Drill
          Issue Type: Bug
          Components: Client - JDBC
    Affects Versions: 1.11.0
         Environment: 5 node x 8GB Drill cluster deployed on Kubernetes.
            Reporter: Paul Makkar


I am running a CTAS query on an s3 bucket with 500 compressed json files - ouput as parquet.

Query ran from command line:
/opt/drill/apache-drill-1.11.0/bin/sqlline --verbose=true --showWarnings=true --showNestedErrs=true
--force=true --run=therm.sql -u jdbc:drill:zk-k8s-drill:2181

therm.sql:
use `s3`.`drill-output`; *(s3 points to kairos bucket)
alter session set `store.format`='parquet';
ALTER SESSION SET `store.json.all_text_mode` = true;
create table temps_bucket0 as select t.id, t.`value` as temp, to_timestamp(cast(substr(t.`timestamp`,1,10)
as int)) as ts, t.device_id from `s3`.`bucket=0/` as t where cast(t.`timestamp` as int) >
1475280000 and cast(t.`timestamp` as int) < 1491004799;

Drill ran for 17 min 50.246 sec and managed to write approx. 100M records then failed with
the following message (see below). I tried to download and uncompress the file manually and
it is corrupt. Ideally, Drill should log but skip the corrupt file.
