> Improve and Expand Text-Based SerDes
> ------------------------------------
>
> Key: HIVE-22337
> URL: https://issues.apache.org/jira/browse/HIVE-22337
> Project: Hive
> Issue Type: Improvement
> Components: Serializers/Deserializers
> Affects Versions: 4.0.0
> Reporter: David Mollitor
> Assignee: David Mollitor
> Priority: Major
> Labels: pull-request-available
> Fix For: 4.0.0
>
> Attachments: HIVE-22337.1.patch
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> * 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.
> {code:none|title=CSV SerDe}
> "1,2,3" = ["1","2","3"]
> "1,2," = ["1","2",null]
> "" = [null,null,null]
> "1,2,3,4" = ["1","2","3,4"]
> {code}
