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.
