Hi, My UI for hadoop 20.2 on a single machine suddenly is giving the following errors for NN and JT web-sites respectively:
HTTP ERROR: 404 /dfshealth.jsp RequestURI=/dfshealth.jsp *Powered by Jetty:// <http://jetty.mortbay.org/>* HTTP ERROR: 503 SERVICE_UNAVAILABLE RequestURI=/jobtracker.jsp *Powered by jetty:// <http://jetty.mortbay.org/>* The only thing I think of, is that I also installed version 21.0 , but had problems so I shut it off and went back to 20.2. When I check the system using 'fsck' everything looks fine though. Let me know what you think. Thank, Mark
