Re: TaskTracker: Can not start task tracker because
java.lang.RuntimeException: Not a host:port pair: local
Hi David,
The --config parameter to hadoop expects a configuration directory, not a
file. Your file still needs to be named hadoop-site.xml (or in newer
versions core-site, hdfs-site, or mapred-site.xml)
Hope that helps
-Todd
