[SPARK-16757] Set up Spark caller context to HDFS
## What changes were proposed in this pull request?
1. Pass `jobId` to Task.
2. Invoke Hadoop APIs.
A new function `setCallerContext` is added in `Utils`. `setCallerContext`
function invokes APIs of `org.apache.hadoop.ipc.CallerContext` to set up
spark caller contexts, which will be written into `hdfs-audit.log`.
For applications in Yarn client mode, `org.apache.hadoop.ipc.CallerContext`
are called in `Task` and Yarn `Client`. For applications in Yarn cluster mode,
`org.apache.hadoop.ipc.CallerContext` are be called in `Task` and
`ApplicationMaster`.
The Spark caller contexts written into `hdfs-audit.log` are applications'
name` {spark.app.name}` and `JobID_stageID_stageAttemptId_taskID_attemptNumbe`.
## How was this patch tested?
Manual Tests against some Spark applications in Yarn client mode and Yarn
cluster mode. Need to check if spark caller contexts are written into HDFS
hdfs-audit.log successfully.
For example, run SparkKmeans in Yarn client mode:
`./bin/spark-submit --master yarn --deploy-mode client --class
org.apache.spark.examples.SparkKMeans
examples/target/original-spark-examples_2.11-2.1.0-SNAPSHOT.jar
hdfs://localhost:9000/lr_big.txt 2 5`
Before:
There will be no Spark caller context in records of `hdfs-audit.log`.
After:
Spark caller contexts will be in records of `hdfs-audit.log`.
(_Note: spark caller context below since Hadoop caller context API was
invoked in Yarn Client_)
