abstractdog opened a new pull request, #6436:
URL: https://github.com/apache/hive/pull/6436
### What changes were proposed in this pull request?
Make LlapTaskSchedulerMetrics initialization idempotent. This hits in
testing scenarios, where in the case of a tez LocalClient against llap, the
llap scheduler metrics can be initialized multiple times (which is not the case
in a real world cluster, where a TezAM initializes this only once).
### Why are the changes needed?
See the issue description on Jira.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Tested pre-patch, see Jira.
Post patch, with the latest changes:
```
# build hive
mvn install -DskipTests -nsu -Pdist
cp packaging/target/apache-hive-4.3.0-SNAPSHOT-bin.tar.gz packaging/cache

# do the pre-patch testing to confirm
./stop-hive.sh --cleanup
...
```
