I've created a parquet file using Pyarrow and it can be queried using Pyspark. However it cannot be queried using Apache-drill(1.14), which was installed recently and can work with other data formats including csv, json and RDBs. Can someone help me troubleshooting what's going wrong and how can i fix it? Thanks!
(I was able to run the count(*) query but cannot run query below)
Here is my query and the error message:
select * from dfs.`C:/Apache_Spark/sample_Sends_2017.parquet` limit 20;
Query execution failed
Reason:
SQL Error: INTERNAL_ERROR ERROR: Error in parquet record reader.
