yarn in cluster

Explorer

Hi,

 

I've got little hadoop cluster with yarn as resource manager.

Everything works fine except  jobhistory.

When I run yarn job history it points me to backup server not my primary.

I also get message :"

Aggregation may not be complete, Check back later or try the nodemanager".

I have second cluster with the same configuration which works fine...

Can anyone point me what can be wrong ?

 

Best regards,

 

Morbious
