Fengnan Li commented on HDFS-14327: ----------------------------------- [~elgoiri] up ^^ thanks a lot! > Using FQDN instead of IP to access servers with DNS resolving > ------------------------------------------------------------- > > Key: HDFS-14327 > URL: https://issues.apache.org/jira/browse/HDFS-14327 > Project: Hadoop HDFS > Issue Type: Improvement > Reporter: Fengnan Li > Assignee: Fengnan Li > Priority: Major > Attachments: HDFS-14327.001.patch, HDFS-14327.002.patch > > > With [HDFS-14118|https://issues.apache.org/jira/browse/HDFS-14118], clients > can get the IP of the servers (NN/Routers) and use the IP addresses to access > the machine. This will fail in secure environment as Kerberos is using the > domain name (FQDN) in the principal so it won't recognize the IP addresses. > This task is mainly adding a reverse look up on the current basis and get the > domain name after the IP is fetched. After that clients will still use the > domain name to access the servers. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
