Naveen Pishe created SPARK-12214: ------------------------------------ Summary: Spark to provide an API to save user-defined metadata as part of Sequence File header 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 Reporter: Naveen Pishe
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 Creating a Union of two RDD (header + data) and saving as Sequence file is not a solution as its not a header. Is there any way I can achieve the same. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
