> The JSON SerDe has a few issues, I will link them to this JIRA.
> * Use Jackson Tree parser instead of manually parsing
> * Added support for base-64 encoded data (the expected format when using JSON)
> * Added support to skip blank lines (returns all columns as null values)
> * Current JSON parser accepts, but does not apply, custom timestamp formats
> in most cases
> * Added some unit tests
> * Added cache for column-name to column-index searches, currently O\(n\) for
> each row processed, for each column in the row
