下午好，我在尝试访问 http://:7070 时遇到问题。我安装了以下程序： apa​​che-hive-3.1.2-bin 、 kylin-3.1.1-bin-hadoop3 、 kafka_2.12-2.5.0 、 hadoop-3.3.0 和 hbase-2.3.4 我倾向于认为它与连接到 HBase 时的一些问题有关，因为每当我运行一个列表时，它都会给我以下错误：

hbase(main):001:0> list
TABLE                                                                                                                                         

ERROR: org.apache.hadoop.hbase.ipc.ServerNotRunningYetException: Server is not running yet
    at org.apache.hadoop.hbase.master.HMaster.checkServiceStarted(HMaster.java:2921)

    at org.apache.hadoop.hbase.ipc.RpcExecutor$Handler.run(RpcExecutor.java:318)

当我在 HBase 的日志中搜索时，我得到以下结果：

$ less hbase-2.3.4/logs/hbase-cuquerella-master-tfg.log

        at org.apache.hadoop.hbase.master.HMaster.finishActiveMasterInitialization(HMaster.java:948)

如果有人能阐明这个问题，我将不胜感激。对于我在问这个问题时所犯的任何错误，我深表歉意，因为我是一个真正的初学者。

您的 HMaster 似乎没有运行。你的 Hadoop 平台是什么？HDP还是CDH？在 Ambari 或 Cloudera Manager 中检查 HMaster 的状态，如果需要重新启动它。
