-----------------------------------

             Summary: During the initialization process of the log thread, the 
SparkEnv is empty, which leads to failure
                 Key: KYLIN-5330
                 URL: https://issues.apache.org/jira/browse/KYLIN-5330
             Project: Kylin
          Issue Type: Bug
    Affects Versions: 5.0-alpha
            Reporter: sibing.zhang
             Fix For: 5.0-alpha
         Attachments: image-2022-12-05-16-07-08-594.png

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.
