https://github.com/apache/spark/pull/7158
[SPARK-8755][Streaming]Login user before reading the checkpoint file in
hdfs.
If the user set `spark.yarn.principal` and `spark.yarn.keytab` , he does
not need `kinit` in the client machine.
But when the application was recorved from checkpoint file, it had to
`kinit`, because:
The checkpoint did not use this configurations before it use a DFSClient to
fetch the ckeckpoint file.
But there is a small problem, the
`UserGroupInformation.loginUserFromKeytab` will be called twice in checkpoint
application. Ignored it in this PR.
