Allen Wittenauer commented on HDFS-1326:
----------------------------------------
So in other words, yes.
For Solaris, I think the patch used in HDFS-1150 would work unmodified save two
things:
a) need to remove the uid 0 check
b) need to include directions on setting PRIV_NET_PRIVADDR to the HDFS user's
role
We could optionally set tcp_extra_priv_ports to include >1024 ports dedicated
to HDFS if we didn't want to use a 'real' privileged port.
I suspect SELinux capabilities are configured similarly.
