Description of PR

JIRA: MAPREDUCE-7522. Fix SpotBugs issues in hadoop-mapreduce-client-app module.

After upgrading SpotBugs to version 4.9.7 in #8028, the new analysis rules identified several code quality issues in the hadoop-mapreduce-client-app module.

This update focuses on fixing these newly reported SpotBugs warnings to eliminate potential risks such as null pointer exceptions and resource leaks, ensuring successful builds and maintaining code consistency.

How was this patch tested?

CI.

For code changes:

  • Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799. Your PR title ...')?
  • Object storage: have the integration tests been executed and the endpoint declared according to the connector-specific documentation?
  • If adding new dependencies to the code, are these dependencies licensed in a way that is compatible for inclusion under ASF 2.0?
  • If applicable, have you updated the LICENSE, LICENSE-binary, NOTICE-binary files?
