[jira] [Commented] (APEXMALHAR-2314) Improper functioning in partitioning of sequencialFileRead property of FSRecordReader

    APEXMALHAR-2314 Improper functioning in partitioning for sequencialFileRead for FSRecord

    Fix the StreamCodec for FSRecordReader, initially it was hashcode of blockId's mostly always unique.
    Hence unable to satisfy the sequencialFileRead property. Now the StreamCodec is modified to work
    with hashcode of filePath. So all blocks related to a file would be partitioned on same operator.
    
    Tested with recordReader and verified for sequencialFileRead that all blocks related to a file are partitioned to single operator.
