Pieter Reuse commented on HDFS-6708:
------------------------------------

Hi [~arpitagarwal], we found this ticket while looking at [HDFS-9806|https://issues.apache.org/jira/browse/HDFS-9806].
It looks like this ticket should be implemented for block replicas on external storages. Did
you have a chance to look at this?

> HDFS-6702 is adding support for file creation based on StorageType.
> The block token is used as a tamper-proof channel for communicating block parameters
from the NN to the DN during block creation. The StorageType should be included in this block
token.
