Oh, forgot to mention that the version I use is 0.20.203.0. -----Original Message----- From: 叶达峰 [mailto:kobe082...@qq.com] Sent: 2011年6月23日 0:29 To: common-dev Subject: Hadoop Eclipse plugin 0.20.203.0 doesn't work
Hi, I am a freshman on Hadoop. Today, I spent the whole night trying to set up a development environment for Hadoop. I encounter several problems, first is that the eclipse can't load the plugin, I changed to another version, this problem was resolved. But now, I have one more difficult problem. I try to set up Map/Reduce Location, if everything were well, it should connect to the server and the DFS Location could list the whole file system. Sadly, it doesn't work. I have checked to configuration several times, it should be correct. Here is the message I get: Error: failure to login An internal error occured during: "Map/reduce location status updater." org/codehaus/jackson/map/jsonmappingexception
