[jira] [Created] (YARN-9118) Handle issues with parsing user
defined GPU devives in GpuDiscoverer
Szilard Nemeth created YARN-9118:
------------------------------------
Summary: Handle issues with parsing user defined GPU devives in GpuDiscoverer
Key: YARN-9118
URL: https://issues.apache.org/jira/browse/YARN-9118
Project: Hadoop YARN
Issue Type: Bug
Reporter: Szilard Nemeth
Assignee: Szilard Nemeth
getGpusUsableByYarn has the following issues:
- Duplicate GPU device definitions are not denied: This seems to be the biggest issue as it could increase the number of devices on the node if the device ID is defined 2 or more times.
- An empty-string is accepted, it works like the user would not want to use auto-discovery and haven't defined any GPU devices: This will result in an empty device list, but the empty-string check is never explicitly there in the code, so this behavior just coincidental.
- Number validation does not happen on GPU device IDs (separated by commas)
Many testcases are added as the coverage was already very low.
