I believe the debug logs location is still specified in hadoop-env.sh (I just read the 0.19.0 doc). I think you have to shut down all nodes first (stop-all), then format the namenode, and then restart (start-all) and make sure that NameNode comes up too. We are using a very old version, 0.12.3, and are upgrading. -TCK

I would check the hadoop namenode logs to see if there was some startup problem (the location of those logs would be specified in hadoop-env.sh, at least in the version I'm using). -TCK --- On Wed, 2/4/09, Mithila Nagendra <[email protected]> wrote: From: Mithila Nagendra <[email protected]> Subject: Bad connection to FS. To: "[email protected]" <[email protected]>, "[email protected]" <[email protected]> Date: Wednesday, February 4, 2009, 6:06 PM Hey all When I try to copy a folder from the local file system in to the HDFS using the command hadoop dfs -copyFromLocal, the copy fails and it gives an error which says "Bad connection to FS". How do I get past this? The following is the output at the time of execution: had...@renweiyu-desktop:/usr/local/hadoop$ jps 6873 Jps 6299 JobTracker 6029 DataNode 6430 TaskTracker 6189 SecondaryNameNode had...@renweiyu-desktop:/usr/local/hadoop$ ls bin docs lib README.txt build.xml hadoop-0.18.3-ant.jar libhdfs src c++ hadoop-0.18.3-core.jar librecordio webapps CHANGES.txt hadoop-0.18.3-examples.jar LICENSE.txt conf hadoop-0.18.3-test.jar logs contrib hadoop-0.18.3-tools.jar NOTICE.txt had...@renweiyu-desktop:/usr/local/hadoop$ cd .. had...@renweiyu-desktop:/usr/local$ ls bin etc games gutenberg hadoop hadoop-0.18.3.tar.gz hadoop-datastore include lib man sbin share src had...@renweiyu-desktop:/usr/local$ hadoop/bin/hadoop dfs -copyFromLocal gutenberg gutenberg 09/02/04 15:58:21 INFO ipc.Client: Retrying connect to server: localhost/ 127.0.0.1:54310.

The commmand jps shows that the hadoop system s up and running. So I have no idea whats wrong! Thanks! Mithila
