Hi I am using the Sandbox 2.3.2

I just download it 2 weeks ago.

At the first week before I am running with 4 GB RAM. Then i request it to my team to upgrade memory to 8 GB.

But the Resource Manager YARN and Ambari Server Alert cannot be started. always CRIT

Please what do i miss ?

Thank you

yan

@yan Adiputra Just looking at your logs, looks like the problem is a wrong memory configuration:

2015-12-10 09:57:39,443 INFO  service.AbstractService (AbstractService.java:noteFailure(272)) - Service RMActiveServices failed in state INITED; cause: org.apache.hadoop.yarn.exceptions.YarnRuntimeException: Invalid resource scheduler memory allocation configuration, yarn.scheduler.minimum-allocation-mb=3072, yarn.scheduler.maximum-allocation-mb=2250, min and max should be greater than 0, max should be no smaller than min.

According to the logs the following config is set:

yarn.scheduler.maximum-allocation-mb=2250
yarn.scheduler.minimum-allocation-mb=3072

This config is impossible min has to be smaller than max

Could you please switch the configurations, so that you have:

yarn.scheduler.maximum-allocation-mb=3072
yarn.scheduler.minimum-allocation-mb=2250

Hi Jonas,

I checked the sandbox on latest version, by default we use a min container of 250MB and max container 2250MB.

@rmolina thanks for checking 🙂

Is there a possibility for upgrading the memory from 4GB to 8 gb?

Hi Team,

Can any one help to resolve this issue, Resources manager wnet down due to this not able start them.

Error:-
Service did not start successfully; not all of the required roles started: only 23/25 roles started. Reasons : Service has only 0 ResourceManager roles running instead of minimum required 1.
