I am working with complex data type in impala table and getting error while query the complex data type column in impala.

I followed below steps.

1. Created parquet file using spark .

2. create impala table with complex data type column (ARRAY<string>)

3. load parquet file created in step 1 into impala table.

File 'hdfs://xyz.parquet' has an incompatible Parquet schema for column 'abc'. Column type: array, Parquet schema: optional byte_array abc [i:5 d:1 r:0]
