我正在尝试使用Hortonworks hbase连接器将Spark 2.0与hbase（https://github.com/hortonworks-spark/shc/tree/v1.1.0-2.0）配合使用
在上面的链接中提供了示例，
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
在执行spark2之后，提交作业运行并仅打印架构。后来，所有的准考官都已存在并永远被困住。
日志中的最后一条消息：
现有执行程序41已被删除（新总数为1）
但是我可以成功地按顺序使用Hbase，即put或BulkPut，但不能使用RDD或DF（使用任何hbase连接器）在Spark中工作。
由于哪个spark executor无法并行工作，hbase / spark配置是否存在任何错误？或工作节点中缺少什么？
工作者发出的错误消息：
