Hi, I'm a fresh people of Mesos usage, and recently I tried to follow the instructions in https://github.com/mesos/hadoop/blob/master/README.md to setup the Hadoop running on Mesos. Now I get a problem that the Hadoop is not displayed under list of Mesos Web UI "Active Frameworks". I want to know what I have missing to get the framework registered with Mesos, or is it necessary in this case?
Here is some env information: Hadoop running with following services: $ jps 12375 JobTracker 12839 TaskTracker 11325 DataNode 11267 NameNode 12895 Jps The log from jobtracker is showing Mesos is doing some job: I0704 00:33:24.501077 12460 master.cpp:2273] Processing ACCEPT call for offers: [ 20150704-001951-2397939904-59631-12375-O160 ] on slave 20150704-001951-2397939904-59631-12375-S0 at slave(1)@192.168.237.142:59631 (kilo) for framework 20150704-001951-2397939904-59631-12375-0000 (hadoop) at scheduler-0ab6c7e5-fb4f-4951-9086-cc9efc3c27a4@192.168.237.142:59631 I0704 00:33:24.501871 12457 hierarchical.hpp:648] Recovered cpus(*):2; mem(*):2921; disk(*):10618; ports(*):[31000-32000] (total allocatable: cpus(*):2; mem(*):2921; disk(*):10618; ports(*):[31000-32000]) on slave 20150704-001951-2397939904-59631-12375-S0 from framework 20150704-001951-2397939904-59631-12375-0000 I0704 00:33:29.508990 12457 master.cpp:3760] Sending 1 offers to framework 20150704-001951-2397939904-59631-12375-0000 (hadoop) at scheduler-0ab6c7e5-fb4f-4951-9086-cc9efc3c27a4@192.168.237.142:59631 15/07/04 00:33:29 INFO mapred.ResourcePolicy: JobTracker Status Pending Map Tasks: 0 Pending Reduce Tasks: 0 Running Map Tasks: 0 Running Reduce Tasks: 0 Idle Map Slots: 0 Idle Reduce Slots: 0 Inactive Map Slots: 0 (launched but no hearbeat yet) Inactive Reduce Slots: 0 (launched but no hearbeat yet) Needed Map Slots: 0 Needed Reduce Slots: 0 Unhealthy Trackers: 0 Thanks a lot.
