WIP CDPD-8989 Improve admission control pool stats logging to be more
explicit
This work addresses the current limitation in admission controller by
appending the last known memory consumption statistics about a host to
the existing host memory exhaustion message. The message is logged in
impalad.INFO when a query is queued or timed out due to memory exhaustion
at the host.
This new memory consumption statistics covers the following content:
num_running: the total number of queries running
top_queries: a list of query Ids for up to 5 queries with top memory
consumptions
min: the minimal memory consumption of all running queries
max: the maximal memory consumption of all running queries
total: the total memory consumption of all running queries
average: the average memory consumption of all running queries
One example of the appended string is as follows.
Memory consumed: num_running=2, top_queries=[
dc4fd356433812be:6902546f00000000, c54d5ab3f4773ee8:8fb6a62800000000],
min=12.30 MB, max=12.37 MB, total=24.67 MB, average=12.34 MB
Testing:
TBD
