------------------------------------
Summary: YarnClient throws NoClassDefFoundError for
WebSocketException with only shaded client jars
Key: YARN-10314
URL: https://issues.apache.org/jira/browse/YARN-10314
Project: Hadoop YARN
Issue Type: Bug
Components: yarn
Affects Versions: 3.3.0
Reporter: Vinayakumar B
After YARN-8778, with only shaded hadoop client jars in classpath Unable to
submit job.
CC: [~ayushtkn] confirmed the same. Hive 4.0 doesnot work due to this, shaded
client is necessary there to avoid guava jar's conflicts.
