我正在尝试使用hortonworks hbase connector for spark 2.0来处理hbase(https://github.com/hortonworks-spark/shc/tree/v1.1.0-2.0)
通过上面链接中提供的示例，

val spark = SparkSession
      .builder()
      .appName(getClass.toString)
      .getOrCreate()

def withCatalog(cat: String, spark: SparkSession): DataFrame = {
    spark
      .read
      .options(Map(HBaseTableCatalog.tableCatalog->cat))
      .format("org.apache.spark.sql.execution.datasources.hbase")
      .load()
  }
    val df = withCatalog(cat, spark)
    df.printSchema()
    df.show(20, false)

架构：

val cat =
         s"""{
            |"table":{"namespace":"test", "name":"test_src_data", "tableCoder":"PrimitiveType"},
            |"rowkey":"tfkod_description",
            |"columns":{
            |"col0":{"cf":"rowkey", "col":"tfkod_description", "type":"string"},
            |"src_stream_desc":{"cf":"src_data", "col":"src_desc", "type":"string"}
            |}
            |}""".stripMargin

完成spark2之后，提交作业运行并只打印模式。后来所有的执行者都存在并永远被卡住了。
日志中的最后一条消息：
现有执行人41已被移除（新的总数为1）
但我可以成功地以顺序方式使用hbase，即put或bulkput，而不是rdd或df（使用任何hbase连接器）的方式在spark中工作。
hbase/spark配置中是否有任何错误是由于哪个spark执行器不能并行工作造成的？或者工作节点中缺少什么？
来自工作进程的错误消息：
