Rahul Challapalli created DRILL-2293:
----------------------------------------

             Summary: CTAS does not clean up when it fails
                 Key: DRILL-2293
                 URL: https://issues.apache.org/jira/browse/DRILL-2293
             Project: Apache Drill
          Issue Type: Bug
          Components: Storage - Parquet
            Reporter: Rahul Challapalli
            Assignee: Steven Phillips


git.commit.id.abbrev=6676f2d

Data Set :
{code}
{
  "id" : 1,
  "map":{"rm": [
    {"mapid":"m1","mapvalue":{"col1":1,"col2":[0,1,2,3,4,5]},"rptd": [{ "a": "foo"},{"b":"boo"}]},
    {"mapid":"m2","mapvalue":{"col1":0,"col2":[]},"rptd": [{ "a": "bar"},{"c":1},{"d":4.5}]}
  ]}
}
{code}

The below query fails :
{code}
create table rep_map as select d.map from `temp.json` d;
Query failed: Query stopped., index: -4, length: 4 (expected: range(0, 16384)) [ d76e3f74-7e2c-406f-a7fd-5efc68227e75
on qa-node190.qa.lab:31010 ]
{code}

However drill created a folder 'rep_map' and the folder contained a broken parquet file. 
{code}
create table rep_map as select d.map from `temp.json` d;
+------------+------------+
|     ok     |  summary   |
+------------+------------+
| false      | Table 'rep_map' already exists. |
{code}

Drill should clean up properly in case of a failure.

I raised a different issue for the actual failure.
