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?

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.
