[jira] [Created] (HDFS-6708) StorageType should be encoded in the block token

Arpit Agarwal created HDFS-6708:
-----------------------------------

             Summary: StorageType should be encoded in the block token
                 Key: HDFS-6708
                 URL: https://issues.apache.org/jira/browse/HDFS-6708
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: datanode, namenode
    Affects Versions: 2.4.1
            Reporter: Arpit Agarwal


HDFS-6702 is adding support for file creation based on StorageType.

Since the client acts as an intermediary between the NN and the DN to facilitate block creation the StorageType needs to be encoded in the block token for security reasons, so any StorageType quota checks performed by the NameNode cannot be bypassed.
