Question

你好，有人可以帮助我一个新手，因为hadoop想要尝试这个功能。所以你们中的任何人都可以帮忙。我在单个节点集群上运行。

$ hdfs zkfc
Exception in thread "main" org.apache.hadoop.HadoopIllegalArgumentException: HA is not enabled for this namenode.
    at org.apache.hadoop.hdfs.tools.DFSZKFailoverController.setConf(DFSZKFailoverController.java:122)
    at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:66)
    at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:84)
    at org.apache.hadoop.hdfs.tools.DFSZKFailoverController.main(DFSZKFailoverController.java:168)

Answer 1

Answer 2

$ sudo service hadoop-hdfs-namenode start

$ sudo -u hdfs hdfs namenode -bootstrapStandby
