There is a null pointer exception in the yarn application log file. !image-2022-12-05-16-07-08-594.png! *root cause:* When SparkEnv has not been initialized, the log thread executes the SparkEnv.get operation first, causing NPE problems. *fix design:* When SparkEnv.get is executed, it will cause a null pointer exception. If SparkEnv cannot be obtained, the new org.apache.hadoop.conf.Configuration object will be ** used. -- This message was sent by Atlassian Jira (v8.20.10#820010)
