Cgroups error using Impala with Llama

Hello,

 

I'm attempting to configure Llama for resource management. I've successfully set up the AM Server and clients throughout my cluster, but I'm receiving the following error when issuing queries in impala-shell:

 

Query: select * from applogsparquet limit 10

ERROR: CGroup /var/lib/impala/f64cea8e31101f28_a7883b1a4c9fa184_impala does not have a /tasks file

 

Any advice?  Undocumented configuration entries and/or impalad startup options?

 

Thanks,

 

Charlie

Re: Cgroups error using Impala with Llama

Hi -

 

Sorry for the slow reply. What did you set your --cgroup_hierarchy_path command line flag to? It looks like /var/lib/impala - that's probably not a mounted cgroup hierarchy.
