maprlogin Command Examples

Generating and Displaying User Ticket

Generate a user ticket:

$ maprlogin password
[Password for user 'juser' at cluster 'my.cluster.com': ] 
MapR credentials of user 'juser' for cluster 'my.cluster.com' are written to '/tmp/maprticket_1000'

$ maprlogin print
Opening keyfile /tmp/maprticket_1000
my.cluster.com:
user = juser, created = 'Sun Nov 24 18:59:43 PST 2013', expires = 'Sun 
Dec 08 18:59:43 PST 2013', RenewalTill = 'Tue Dec 24 18:59:43 PST 2013',
uid = 1000, gids = 1000, 4, 24, 27, 30, 46, 109, 124 

Generating and Displaying Service Ticket

Generate a service ticket, longlived_ticket, in /tmp for maprUser1:

$ maprlogin generateticket -type service -out /tmp/ticketwithduration -duration 30:0:0 -renewal 90:0:0 -user maprUser1
MapR credentials of user 'maprUser1' for cluster 'JSKCluster129_secure' are written to '/tmp/longlived_ticket'

Display the service ticket in a specified location:

$ maprlogin print -ticketfile /tmp/ticketwithduration
Opening keyfile /tmp/ticketwithduration
JSKCluster129_secure: user = maprUser1, created = 'Tue Jun 14 11:12:01 PDT 2016', 
expires = 'Thu Jul 14 11:12:01 PDT 2016', RenewalTill = 'Mon Sep 12 11:12:01 PDT 2016', 
uid = 0, gids = 0, CanImpersonate = false

Generating and Printing Service with Impersonation Ticket

Generate a service with impersonation ticket (in /var/tmp) for mapruser1:

$ maprlogin generateticket -type servicewithimpersonation -user mapruser1 -out /var/tmp/impersonationTicketMapRuser1

After generating the ticket, ensure that mapruser1 has read permissions on the ticket. If you move the ticketfile to a different location, set the $MAPR_TICKETFILE_LOCATION environment variable.

Display the service with impersonation ticket in the specified location:

$ maprlogin print -ticketfile /var/tmp/impersonationTcketMapruser1
Opening keyfile /var/tmp/impersonationTcketMapruser1
JSKCluster129_secure: user = mapruser1, created = 'Mon Apr 18 13:46:38 PDT 2016', 
expires = 'Mon May 02 13:46:38 PDT 2016', RenewalTill = 'Wed May 18 13:46:38 PDT 2016', 
uid = 501, gids = 502, CanImpersonate = true

Generating and Displaying Cross-cluster Ticket

Generate a cross-cluster ticket (in /tmp) for maprUser1:

$ maprlogin generateticket -type crosscluster -out /tmp/CrossClusterTicket -user maprUser1
MapR credentials of user 'maprUser1' for cluster 'JSKCluster128_secure' are written to '/tmp/CrossClusterTicket'

Display the contents of a cross-cluster ticket in the specified location:

$ maprlogin print -ticketfile /tmp/crossclusterTicket
Opening keyfile /tmp/crossclusterTicket
ClusterSecure: user = root, created = 'Fri May 27 14:29:40 PDT 2016', 
expires = 'Fri May 27 14:29:40 PDT 12016', RenewalTill = 'Fri May 27 14:29:40 PDT 12016', 
uid = 0, gids = 0, CanImpersonate = false

Running an Authentication Test

authtest: This troubleshooting option simulates the behavior of the runtime during authentication, going through the authentication flow.

Options: [ -cluster ] Specifies the name of the cluster.

Ending a Session Before the Ticket Expires

end or logout: Destroys tickets and logs out.

Options: [ -cluster ] Specifies the name of the cluster. By default, deletes all tickets for all clusters.

Renewing a Ticket Before It Expires

renew: Renews an existing ticket for a specified time period.

Options: [ -cluster ] Specifies the name of the cluster. [ -duration ] Specifies the ticket duration.

The duration you specify must be valid for the ticket in question, given the original -renewal value for the ticket and the life of the ticket when the renew command is run:

• You cannot renew a ticket that has already expired.
• You can renew the same ticket multiple times.
• The renewal period (or periods) cannot exceed the available time left for the ticket.

For example, assume that a ticket is created with a duration of 10 days and a renewal of 30 days:

maprlogin password -duration 10:0:0 -renewal 30:0:0

• On the 11th day, the ticket expires and cannot be renewed at all.
• On the 9th day, you can renew the ticket for any number of days up to a maximum of 21.
• On the 23rd day, you can renew the ticket for any number of days up to a maximum of 7.

Example: Renew a ticket and display the renewed ticket in the specified location:

$ maprlogin renew -out /tmp/RenewedsecureClusterTicket -ticketfile /tmp/secureClusterTicket -duration 1:0:0
$ maprlogin print -ticketfile /tmp/RenewedsecureClusterTicket
Opening keyfile /tmp/RenewedsecureClusterTicket
JSKCluster129_secure: user = root, created = 'Tue Jun 07 11:53:29 PDT 2016', 
expires = 'Wed Jun 08 11:56:56 PDT 2016', RenewalTill = 'Thu Jul 07 11:53:29 PDT 2016', 
uid = 0, gids = 0, CanImpersonate = false
