Should running ./bin/hdfs from the source root work?
I get these errors:
[kirk@bubbas apache]$ ./bin/hdfs namenode
./bin/hdfs: line 154: cygpath: command not found
./bin/hdfs: line 177: exec: : not found
I can hack around the latter by setting the JAVA env var up first:
export JAVA=$JAVA_HOME/bin/java
Still, I get this:
[kirk@bubbas apache]$ ./bin/hdfs namenode
./bin/hdfs: line 154: cygpath: command not found
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/hadoop/hdfs/server/namenode/NameNode

Could not find the main class:
org.apache.hadoop.hdfs.server.namenode.NameNode. Program will exit.
This is after running a build (`ant compile`) on the source.
I can dig into it, but I'm wondering if running from source/stand-alone
like this is even expected to work.

Thanks a lot Eli, it really helped a lot. I think I got the general idea of
the scripts.
Thanks,

Hey Andre,
You can run an hdfs build out of common/hdfs trees checked out from
svn or git. Here are some scripts that make this easier:

Hi,
I have clone the repo for hadoop-common and hadoop-hdfs and built it
using
"ant mvn-install" . Now I would like to be able run HDFS in
pseudo-distributed mode to test some modifications of mine. One year ago
I
could do it but now I had no luck. The scripts are failing, complaining
about not found files and stuff.
Has anyone succeed recently in doing something similar to what I am
intending to do . Or do I need to generate a tarball and install it ?
Thanks and Regards,
André
