when I study HDFS,I encounter one question,I want to make hadoop read the confighration file again,because I have changed the file, when stay hadoop open。and I don't want to reboot the hadoop service!
thank you very much!
- fully reload configuration files like hdfs-site.xml/core-site.xml without a restart is not supported.
However, you can change certain configuration keys without a restart using
hdfs dfsadmin [-reconfig <namenode|datanode> <host:ipc_port> <start|status|properties>]
