Uma Maheswara Rao G commented on HDFS-12872:
--------------------------------------------
HI [~xiaochen], Thanks for working on it. I think it make sense to set
blocktocken at group level to use for calculating DN.
{code}
sb.setBlockToken(blockTokenSecretManager.generateToken(
+ NameNode.getRemoteUser().getShortUserName(),
+ internalBlock, EnumSet.of(mode), b.getStorageTypes(),
+ b.getStorageIDs()));
{code}
Isn't this code common to else part now? should we remove else part code and
make this set for block irrespective of isStriped ?
