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 -- This message was sent by Atlassian JIRA (v7.6.3#76005)
