Xiaobing Zhou updated HDFS-9094:
--------------------------------
Attachment: HDFS-9094-HDFS-9000.008.patch
V008 handled the return code and kept err msg unchanged by restoring it back.
{noformat}
- System.err.println("Node type " + nodeType +
- " does not support reconfiguration.");
- return 1;
+ err.println("Unrecognized node type: '" + nodeType + "'");
{noformat}
Some people in the community complain if we change the output of existing
commands as they think it can break compatibility for existing scripts.
> Add command line option to ask NameNode reload configuration.
