Try adding the hadoop/conf directory in the TOMCAT’s classpath


Ex : CLASSPATH=/usr/local/Apps/hbase-0.90.4/conf:/usr/local/Apps/hadoop-

Subject: Re: Integrating hadoop with java UI application deployed on tomcat


Thanks steve thers nothing in logs and no exceptions as well i found that some file is created in my F:\user with directory name but its not visible inside my hadoop browse filesystem directories i also added the config by using the below method



when running thru WAR printing out the filesystem i m getting org.apache.hadoop.fs.LocalFileSystem@9cd8db 

when running an independet jar within hadoop i m getting DFS[DFSClient[clientName=DFSClient_296231340, ugi=dell]]

when running an independet jar i m able to do uploads....


just wanted to know will i have to add something in my classpath of tomcat or is there any other configurations of core-site.xml that i am missing out..thanks for your help.....

well, it's worked for me in the past outside Hadoop itself:



  1. Turn logging up to DEBUG
  2. Make sure that the filesystem you've just loaded is what you expect, by logging its value. It may turn out to be file:///, because the normal Hadoop site-config.xml isn't being picked up

but the problem is that my  code gets executed with the warning but file is not copied to hdfs , actually i m trying to copy a file from local to hdfs


   Configuration hadoopConf=new Configuration();
        //get the default associated file system
       FileSystem fileSystem=FileSystem.get(hadoopConf);       
       // HarFileSystem harFileSystem= new HarFileSystem(fileSystem);
        //copy from lfs to hdfs
       fileSystem.copyFromLocalFile(new Path("E:/test/GANI.jpg"),new Path("/user/TestDir/"));
