> There appears to be an issue with reading medium to large Parquet files via
> HDFS. We have created a basic Parquet file in with a schema like so:
> sellprice DOUBLE
> When filled with 10,000 double values, the following query in Drill works
> fine:
> select sum(sellprice) from hdfs.`/saleparquet`;
> When filled with 50,000 double values, the following error occurs:
> Query failed: Query stopped.[ 9aece851-48bc-4664-831e-d35bbfbcd1d5 on
> ip-10-8-1-70.ap-southeast-2.compute.internal:31010 ]
> java.lang.RuntimeException: java.sql.SQLException: Failure while executing
> query.
