Each of the Impalad web UI's should provide a way to dump the current state of the daemon (json?), preferably with the following data. Coordinator: - All queries in flight (with query IDs) - Current state of each query ID, along with a timeline - Last report time of each of the fragment instances, for each query ID - Lock diagnostics if a query is blocked on something - Lock diagnostics of the process level locks (like coordinator::lock_ etc..) Executor: - All the fragment instances running at the current time - State of each of the fragment instances - Backtraces of the executor nodes in the fragment instances. - Lock diagnostics if the nodes are blocked on something - Event timeline of each of the executor nodes -- This message was sent by Atlassian JIRA (v7.6.3#76005)
