----------------------------------------
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.
