craigcondit opened a new pull request, #814:
URL: https://github.com/apache/yunikorn-k8shim/pull/814
### What is this PR for?
Replaces sync.{RW}Mutex with internal locking.{RW}Mutex implementations. The
new implementation wraps the go-deadlock library with logic to conditionally
enable deadlock detection based on the presence of environment variables:
To enable the feature:
- DEADLOCK_DETECTION_ENABLED=true
To customize the timeout before potential deadlocks are logged (default is
60 seconds):
- DEADLOCK_TIMEOUT_SECONDS=60
See https://github.com/sasha-s/go-deadlock for more details.
