Hello, This is my second post in the forum and I would like to say that I am amused with the kind of support from other folks. Thanks a lot. Here are few more questions on how stuff works in hadoop:
Q1. What is hdfs://. Actually I ran a -copyFromLocal command and gave source directory as /opt/temp/2.txt and target directory as hdfs://. Later I used the namenode browser to browse through the file system and I can see files listed in "/" location but physically I am unable to see the files in OS. So here is the question what is hdfs://?? Q2. I set the dfs name dir and dfs data dir as following. I know name.dir will store the meta information of what is stored in data nodes. However I do not see anything stored in data.dir? Can some one explain what is this data.dir for? <property> <name>dfs.name.dir</name> <value>file:///opt/ApacheHadoop/nameDir/</value> </property> <property> <name>dfs.data.dir</name> <value>file:///opt/ApacheHadoop/dataDir</value> </property> ++Ashish
