The environment is accessible through the "Map/Reduce perspective" (the blue elephant icon in the top-right side of the main window). Here is an overview of the Eclipse environment for Hadoop: A frequent issue is to have a Java5 execution environment that cannot executes your jobs because your jobs have been compiled with a Java6 compliance level.
Make sure you when you compile your jobs that the Java classes you generate are compatible with the JVM environment of your execution environment.Make sure you build your jobs with the same version of Hadoop as the version of Hadoop your execution environment currently runs. To compile jobs on your development host, you need Hadoop jars.The plug-in has been tested on Eclipse 3.2+ only, using Java5+ compliant JVMs only.To ensure a safe behavior of the plug-in, you should consider the following facts and recommendations: submit jobs and monitor their execution.browse and interact with distributed file systems.create Mapper, Reducer, Driver classes.Among other things, the plug-in provides support to: The Hadoop Eclipse Plug-in provides tools to ease the experience of Map/Reduce on Hadoop. JIRA MAPREDUCE-1280 contains a version of the plugin that works with hadoop 0.20.2 and eclipse 3.5/3.6
The JIRA contains a compiled Plugin JAR you can use for Hadoop 0.20.0 and 0.20.1* JIRA MAPREDUCE-1262 has the latest status for this plugin.
