> The {{versionRequest()}} call does not return any sensitive information.  It is mainly used for sanity checks.   The presence of {{checkSuperuserPrivilege()}} forces users to run datanode as a hdfs superuser.
> In secure setup, a keytab obtained from a compromised datanode can allow the intruder to gain hdfs superuser privilege.  We should allow datanodes to be run as non-hdfs-superuser by removing {{checkSuperuserPrivilege()}} from {{versionRequest()}}.
