Deepak Majeti commented on PARQUET-780:
---------------------------------------
I guess your definition level is incorrect.
Is the first element of your {{def_levels}} array equal to {{0}} ? (Assuming
you are writing a primitive column)
Looking at the call stack, the call below is not the right path when writing a
NULL value.
#1 parquet::DictEncoder<parquet::DataType<(parquet::Type::type)6> >::Put
(v=..., this=0x647840)
at /work/parquet-cpp/src/parquet/encodings/dictionary-encoding.h:332
> WriterBatch API does not properly handle NULL values for byte array types
