Hi folks,
Yarn Client.scala checks the setting from argStrings (passed from
SparkSubmit) and sparkConf (which loads java system properties starting with
spark.* as well). The args settings (--principal, --keytab) will not be
available in spark sql, but we can take advantage of SparkConf with system
properties. Updated the pull request and tested. Please advice if this is what
you are looking for, Thank you!
