Description

Diagnosing NodeManager and container launch problems is made more difficult by the enormous number of logs like

Sending out status for container: container_id {, app_attempt_id {, application_id {, id: 18, cluster_timestamp: 1377559361179, }, attemptId: 1, }, id: 1337, }, state: C_RUNNING, diagnostics: "Container killed by the ApplicationMaster.\n", exit_status: -1000

On an NM with a few containers I am seeing tens of these per second.
