Subject [jira] Commented: (HDFS-1326) Provide pluggable mechanism for securing datanodes
Date Mon, 02 Aug 2010 18:13:17 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1326?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12894629#action_12894629
] 

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.

> As discussed in HDFS-1150, it would be good to allow datanodes to use other methods than
jsvc to secure their ports.
