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

From logs, executors does not have permission to access hdfs file which means executor does not have blocktoken to access datanode.

> Spark thrift server can not impersonate user in kerberos environment.
> I launch spark thrift server in* yarn-client *mode by user *hive* ,which is allowed to impersonate other user.
> User* jt_jzyx_project7* submit sql statement to query its own table located in hdfs catalog: /user/jt_jzyx_project7, and happened errors:
> Permission denied: *user=hive*, access=EXECUTE, inode=*"/user/jt_jzyx_project7*":hdfs:jt_jzyx_project7:drwxrwx---:user:g_dcpt_project1:rwx,group::rwx
> obviously, spark thrift server didn't proxy user: jt_jzyx_project7 .
> And this happened task stage, which means it pass the hive authorization.
