Konstantin Shvachko commented on HDFS-7240: ------------------------------------------- Hey [~anu], read the security document. It's a good one, thanks. Had a question if public-private key replacement of a current use of secrets for block tokens will require a KMS for key management. Thought we can discuss security in a separate jira. > Scaling HDFS > ------------ > > Key: HDFS-7240 > URL: https://issues.apache.org/jira/browse/HDFS-7240 > Project: Hadoop HDFS > Issue Type: New Feature > Reporter: Jitendra Nath Pandey > Assignee: Jitendra Nath Pandey > Priority: Major > Attachments: HDFS Scalability and Ozone.pdf, HDFS Scalability-v2.pdf, > HDFS-7240.001.patch, HDFS-7240.002.patch, HDFS-7240.003.patch, > HDFS-7240.003.patch, HDFS-7240.004.patch, HDFS-7240.005.patch, > HDFS-7240.006.patch, HadoopStorageLayerSecurity.pdf, MeetingMinutes.pdf, > Ozone-architecture-v1.pdf, Ozonedesignupdate.pdf, ozone_user_v0.pdf > > > [^HDFS Scalability-v2.pdf] describes areas where HDFS does well and its > scaling challenges and how to address those challenges.
