IMPALA-6190/6246: Add instances tab and event sequence
This change adds tracking of the current state during the execution of a
fragment instance. The current state is then reported back to the
coordinator and exposed to users via a new tab in the query detail debug
webpage.
This change also adds an event timeline to fragment instances in the
query profile. The timeline measures the time since fragment start at
which particular events complete. Events are derived from the current
state of the execution of a fragment instance. For example:
- Codegen Finished: 79.312ms (79.312ms)
- Prepare Finished: 79.454ms (141.949us)
- Open Finished: 93.287ms (13.832ms)
- First Batch Received: 259.751ms (166.464ms)
- First Batch Sent: 260.219ms (467.917us)
- ExecInternal Finished: 2s733ms (2s473ms)
I added automated tests for both extensions and additionally verified
the change by manual inspection.
