Command line access
Access to HTTP GUIs in the Analytics Cluster is currently very restricted. You must have shell accounts on analytics nodes.
At the very minimum, you must have a shell account on the primary NameNode (analytics1001). HDFS uses POSIX accounts on the NameNode (analytics1001) for granting access to files.
Hue (Hadoop User Experience) GUI is available at https://hue.wikimedia.org. Log in using your UNIX shell username and Wikimedia developer account (Wikitech) password. If you already have cluster access, but can't log into Hue, it is likely that your account needs to be manually synced. Ask an Analytics Opsen (ottomata (aottowikimedia.org) or elukey (ltoscanowikimedia.org) ) -- or file a Phabricator task -- for help.
Admin Instructions to sync a Hue account
When a new Hadoop user is added, an admin should give them a Hue account. Once phab:T127850 is resolved, this process should be automatic.
- Log into http://hue.wikimedia.org
- In the upper right, click on your username, and select Manage Users (you will only be able to do this if you are Hue admin. Another admin can make you one.)
- Click 'Add/Sync LDAP User'
- Fill in the form with their UNIX shell username (not their Wikimedia developer account username), deselect both 'Distinguished name' and 'Create home directory', and click 'Add/Sync user'
If you are in the wmf LDAP group (open to every WMF employee/contractor) and you care only about the Yarn Resource Manager UI, you can login directly to yarn.wikimedia.org.
Otherwise, to send HTTP requests to an internal analytics server, use an SSH tunnel. For example:
To access the Hadoop Resourcemanager jobbrowser, try running:
ssh -N bast1002.wikimedia.org -L 8088:analytics1001.eqiad.wmnet:8088
