> Key: SPARK-12214
> URL: https://issues.apache.org/jira/browse/SPARK-12214
> Project: Spark
> Issue Type: New Feature
> Components: Spark Core
> Affects Versions: 1.3.0, 1.4.0, 1.5.0
> Reporter: Naveen Pishe
> Labels: Sequence, header, metadata, sequencefile
>
> There is requirement to save "user-defined" Metadata as part of Sequence File
> "Header" using Spark.
> To write a User-defined metadata as part of Sequence File using regular
> Hadoop API's I pass the metadata object to SequenceFile.Writer constructor
> which when creates a SequenceFile ensures the metadata is part of the
> sequence file header.
> Currently Spark's JavaPairRDD Api provides methods to save an RDD to an
> SequenceFile format, but I don't see any API which can either give the
> SequenceFile.writer or a method where in I can pass the user-defined metadata
> so as to be written as part of sequence file header.
> The enhancement request an API to implement the same
