一、地址和端口问题

spark官网 说默认端口是 4040，使用spark.ui.port 进行配置spark配置。

我们使用的是CDH，使用 spark.ui.port 查看没有找到该配置

• 搜索 port，找到如下几个端口，看着也就 18088比较像

• 使用如下命令访问

curl http://xxx.xxx.xxx.xxx:18088/api/v1/applications?limit=2

得到如下结果，看着挺像那么回事，仔细一看，怎么都是历史的任务？

[ {
  "id" : "application_1618400751843_125338",
  "name" : "cat3-title-vec",
  "attempts" : [ {
    "startTime" : "2021-05-13T13:33:24.965GMT",

    "lastUpdated" : "2021-05-13T13:34:46.298GMT",
    "duration" : 76586,
    "sparkUser" : "supdev",
    "completed" : true,

    "lastUpdatedEpoch" : 1620912886298,
    "endTimeEpoch" : 1620912881551
  } ]
}, {
  "id" : "application_1618400751843_125318",

    "lastUpdatedEpoch" : 1620912538570,
    "endTimeEpoch" : 1620912538500
  } ]
} ]

• 加上状态

curl "http://sj-20-207-14:18088/api/v1/applications?limit=2&status=running"

还是历史

[ {
  "id" : "application_1618400751843_99465",
  "name" : "Hive on Spark (hiveSessionId = 4f556621-4e68-40d5-a416-8f1fc6a3ea9e)",
