i'm trying parse date stored in cassandra database, but, when parse date, receive error message java.text.parseexception: unparseable date: "[timecol: timestamp]". in database date in format "2015-08-21 04:01:00+0000". can me please?

    val conf = new sparkconf(true)              .set("spark.cassandra.connection.host", "127.0.0.1").setappname("test")              .set("spark.cassandra.connection.port", "9042")              .set("spark.driver.allowmultiplecontexts", "true")              .set("spark.streaming.receiver.writeaheadlog.enable", "true")      val sc = new sparkcontext(conf)     val csc=new cassandrasqlcontext(sc)      val sqlcontext = new org.apache.spark.sql.sqlcontext(sc)       import sqlcontext.implicits._      var imput: simpledateformat   = new simpledateformat("yyyy-mm-dd hh:mm:ss",  locale.english)    var dia: simpledateformat   = new simpledateformat("dd")     val data = csc.sql("select timecol smartgrids.analyzer_temp")    val diacv = dia.format(imput.parse(data.tostring()))

after execute code receive following error message:
