distcp不执行

Question

我试图使用distcp command.following将数据从一个hdfs集群复制到另一个hdfs集群，这是我提交的命令。

hadoop hdfs://sourcenamenodehostname:50070/var/lib/hadoop-hdfs/distcptest.txt hdfs://destinationnamenodehostname:50070/var/lib/hadoop-hdfs

在提交此文件时，我收到了错误消息。请检查错误信息，并引导我走正确的道路。

Answer 1

在我看来，其中一个namenode (源)不健康，不接受入站连接来修改状态或新写。看这个-

Invalid arguments: Operation category READ is not supported in state standby.
