Hi,

We recently tried installing Arangodb 3.1.6 ( Default installation settings 
) on DC/OS 1.8 ( 1 master, 4 agents). However the
arangoDB process goes to unhealthy state and it is not working. We removed 
arangodb based on
the process outlined here : 
https://github.com/arangodb/arangodb3-dcos/issues/2 

But still we were not able to re-install them. We found that though 
arangodb is uninstalled from
DCOS, the system resources were not re-claimed and individual arangodb 
processes were still running 
on the agent machines.

In the services tab, 4 of the tasks are running successfully and one of the 
task is unhealthy, the stderr message in the
unhealthy task is :

I0104 12:20:58.488092    23 CaretakerCluster.cpp:470] And here the offer: 
{"id":{"value":"fe92188a-3138-420b-b6f5-0e91a64dd088-O43919"},"framework_id":{"value":"fe92188a-3138-420b-b6f5-0e91a64dd088-0034"},"slave_id":{"value":"fe92188a-3138-420b-b6f5-0e91a64dd088-S1"},"hostname":"172.22.0.242","url":{"scheme":"http","address":{"hostname":"172.22.0.242","ip":"172.22.0.242","port":5051},"path":"/slave(1)","query":[]},"resources":[{"name":"ports","type":1,"ranges":{"range":[{"begin":1027,"end":2180},{"begin":2182,"end":3887},{"begin":3889,"end":5049},{"begin":5052,"end":8079},{"begin":8082,"end":8180},{"begin":8182,"end":32000}]},"role":"*"},{"name":"disk","type":0,"scalar":{"value":1462},"role":"*"},{"name":"cpus","type":0,"scalar":{"value":7.5},"role":"*"},{"name":"mem","type":0,"scalar":{"value":28173},"role":"*"}],"attributes":[],"executor_ids":[]}

I0104 12:20:58.488116    23 CaretakerCluster.cpp:501] planned DBServer 
instances: 2, running DBServer instances: 1


We able to run other applications such as Spark on DC/OS, hence i feel 
there should not be any problem with 
DCOS.

Another question we have is, is it possible to execute to install versions 
such as 3.0.12 using DCOS.

Regards,
Praveen
