> * Add new SerDe package just for text-based formats: org.apache.hadoop.hive.serde2.text.*
> * Add new SerDe package just for text-based log formats: org.apache.hadoop.hive.serde2.text.log.*
> * Create a coherent hierarchy for processing delimited data: AbstractSerDe -> TextSerDe
-> EncodingAwareTextSerde -> DelimitedSerDe -> CsvTestSerDe
> * Create a coherent hierarchy for processing regex'ed data: AbstractSerDe -> TextSerDe
-> EncodingAwareTextSerde -> RegexSerDe -> CommonFormatLogSerDe
> * Create some standard text processors for super-quick out-of-the-box processing: TSV
SerDe and CSV SerDe
> * Create some standard log processors for super-quick out-of-the-box processing: Apache
Common Log Format and Apache Combined Log Format (Apache HTTP Server Log Parsers)
> * Better default behaviors for processing text
> The default behavior should allow users to quick query data without any failures.
> # When a blank line is encountered, insert a 'null' value for each column
> # When there are fewer fields in the data than defined in the table schema, shift all
available fields left, and fill in 'null' values for all remaining fields
> # When there are too many fields in the data, the last field in the results will contain
all remaining values.  Currently, the data is silently swallows and a warning is issued in
the YARN logs.  A normal user will never see this warning, especially if the job completes
successfully.  Better to (by default) provide them all the data than to hide anything.
