Description

Without -debug parameter, parquet-tools produces quite cryptic output in case of errors. For example, parquet tools may print the following output and nothing more:

org/apache/hadoop/conf/Configuration

It is not clear from this output that it indicates an error (actually it is not clear what it indicates at all). I don't really understand the reasoning behind hiding exceptions by default, but instead of this unusable message, parquet-tools should at least print:

NoClassDefFoundError: org/apache/hadoop/conf/Configuration
