> There is a null pointer exception in the yarn application log file:
> !image-2022-12-05-16-26-36-021.png|width=897,height=163!
> *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.
