由于Apache Kylin错误，无法访问localhost:7070

Question

下午好，我在访问http://:7070时遇到了问题。安装了apache-hive-3.1.2-bin、kylin-3.1.1-bin-hadoop3、kafka_2.12-2.5.0、hadoop . 3.3.0、hbase . 2.3.4等程序我倾向于认为这与连接HBase时的一些问题有关，因为每当我运行列表时，它都会给我以下错误:

hbase(main):001:0> list
TABLE

当我在HBase的log中搜索时，我得到以下结果:

如果有人能说明这个问题，我将非常感激。我为我在问这个问题时所犯的任何错误感到抱歉，因为我是一个真正的初学者。

似乎您的HMaster没有运行。你们的Hadoop平台是什么?HDP还是CDH?检查HMaster在Ambari或Cloudera Manager中的状态，如果需要重启HMaster
