Description

When compiling hbase-spark module against Spark 2.3.0 release, we would get:

[ERROR] /a/hbase/hbase-spark/src/main/scala/org/apache/hadoop/hbase/spark/HBaseContext.scala:68: error: value getCurrentUserCredentials is not a member of org.apache.spark.deploy.        SparkHadoopUtil
[ERROR]   @transient var credentials = SparkHadoopUtil.get.getCurrentUserCredentials()
[ERROR]                                                    ^
[ERROR] /a/hbase/hbase-spark/src/main/scala/org/apache/hadoop/hbase/spark/HBaseContext.scala:236: error: value getCurrentUserCredentials is not a member of org.apache.spark.deploy.       SparkHadoopUtil
[ERROR]     credentials = SparkHadoopUtil.get.getCurrentUserCredentials()
[ERROR]                                       ^
[ERROR] two errors found

getCurrentUserCredentials was removed by SPARK-22372.

This issue is to replace the call to getCurrentUserCredentials with call to UserGroupInformation.getCurrentUser().getCredentials()
