Unable to start NFSGateway : resource_management.core.exceptions.ExecutionFailed

dvt_isoft — Mon, 26 Jun 2017 14:28:53 GMT

Hi,

I juste installed a 4-nodes Hadoop cluster, and I can't start the services because the start-up fails at starting NFSGateway on my 4-th node, where it throws :

resource_management.core.exceptions.ExecutionFailed

The whole error is :

Traceback (most recent call last):

Thanks in advance for your answer !

Sylvain.

HI,

The error reads that the the gateway is already running

nfs3 running as process 3138.Stop it first.

Please check if the nfs process is already running.

It looks like it was indeed. I killed the process and I did not get the error anymore. Thanks.
