Spark hang on load phoenix table

[马骉]

Hi all
    Have you met the problem that submit the job to the Spark, then it just 
hang on? There showed no stage message on the 8080 web UI.
    It seems this is something wrong in 
    val df = sqlContext.load(
  "org.apache.phoenix.spark",
  Map("table" -> "\"test_table\"", "zkUrl" -> "10.17.10.2:2181")
)   Any ideas, please
------------------
Warmest Regards~
