The second code snippet is similar to:
examples//src/main/scala/org/apache/spark/examples/HBaseTest.scala
See the comment in HBaseTest.scala :
// please ensure HBASE_CONF_DIR is on classpath of spark driver
// e.g: set it through spark.driver.extraClassPath property
// in spark-defaults.conf or through --driver-class-path
// command line option of spark-submit
If during execution of TableInputFormatBase#initializeTable(), there was
exception, table field might not have been initialized.
FYI
