I have a requirement, where i need to encrypt certain sensitive data before landing/ingestion into Hadoop. Just want to understand, how Hadoop process these kind of encrypted data(be it in hive or pig or any map-reduce).
Do we need to write specific programs? to read this kind of encrypted files in hadoop or do we need to set any parameters on hive table or pig session to read these this kind of encrypt data ?
Any ideas/thoughts or suggestions ?
