What changes were proposed in this pull request?
Make hive image able to start a TezAM in LLAP mode that can assign tasks to the LLAP daemons.
Why are the changes needed?
Because it's the next step to have a fully distributed, Dockerized environment for Hive.
Does this PR introduce any user-facing change?
No.
How was this patch tested?
Manually, steps are below.
Needs Hive 4.3.0-SNAPSHOT jars that contain recent changes (specifically HIVE-29477):
start cluster:
test:
see logs that queries go through tezam and daemons:
very important test case is that the container layout implemented here in docker-compose is compatible with the already existing and working hs2+llapdeamon setup (no tezam), which is confirmed as:
in which case tezam will simply fail to start, and the cluster works exactly the same way as post-HIVE-29411
be aware of the difference, in case of:
the tez zookeeper-based registry and external sessions code are simply not present, that's why - regardless of the config - here it can work
