Nandor Kollar commented on PIG-4092:
------------------------------------
[~rohini] I upgraded the Parquet to the latest and the constructor of
ParquetInputSplit [parses the schema |
https://github.com/apache/parquet-mr/blob/master/parquet-hadoop/src/main/java/org/apache/parquet/hadoop/ParquetInputSplit.java#L95],
thus invalid schema is not allowed any more. I couldn't find the old code, but
the constructor just set the private schema field before, it didn't parse the
given string. I guess in this test case we can use just a simple dummy schema,
it is not important for the test.
