--------------------------------------
Summary: Null pointer exception in DrillParquetReader when caneled
before data arrives
Key: DRILL-1967
URL: https://issues.apache.org/jira/browse/DRILL-1967
Project: Apache Drill
Issue Type: Test
Reporter: Jason Altekruse
Assignee: Jason Altekruse
To reproduce:
create table my_table select a from json_table.json;
json_table.json:
{
"a" : "a string"
}
{
"a" : 1
}
The schema change will cause an error before a batch is ever sent to the
writer. This causes a null pointer in the cleanup method.
