> h2. Steps to reproduce
> 1. Pass valid --principal=user@REALM and --keytab=/home/user/.keytab to spark-submit
> 2. Set spark.sql.catalogImplementation = 'hive'
> 3. Set deploy mode to yarn-client
> 4. Create a SparkSession and try to use session.createDataFrame()
> h2. Observations
> * The {{setupCredentials}} function in Client.scala sets {{spark.yarn.keytab}} to a UUID suffixed version of the base keytab filename without any path. For example, {{sparkContext.getConf().getAll()}} shows {{spark.yarn.keytab}} as having value {{.keytab-f0b9b814-460e-4fa8-8e7d-029186b696c4}}
> * When listing the contents of the application staging directory on HDFS, no suffixed file exists. Rather, the keytab file appears in the listing with its original name. For instance, {{hdfs dfs -ls hdfs://home/user/.sparkStaging/appication_big_uuid/}} shows an entry {{hdfs://home/user/.sparkStaging/appication_big_uuid/.keytab}}, but not {{hdfs://home/user/.sparkStaging/appication_big_uuid/.keytab-big-uuid}}.
> * The same exception noted above occurs even after I manually put a copy of the keytab with a filename matching the new value of {{spark.yarn.keytab}} onto HDFS in the staging directory.
> h2. Expected Behavior
> HiveClientImpl should be able to read {{spark.yarn.keytab}} to find the keytab file and initialize itself properly.
> h2. References
> * SPARK-8619 also noted trouble with the keytab property getting changed after app startup.
