Hi all,
I'm trying to install a plugin called gfarm_hadoop that allows me to use a
filesystem called gfarm instead of HDFS (
https://sourceforge.net/projects/gfarm/files/gfarm_hadoop/).
I have used it before, but now I'm trying to install it in a new cluster
and for some reason it isn't working...
After installing gfarm 2.5.8 at /data/local3/marilia/gfarm, hadoop 1.1.2 at
/data/local3/marilia/hadoop-1.1.2 and the plugin, when I try to list the
new filesystem it works fine:
$ bin/hadoop fs -ls gfarm:///
Found 26 items
-rwxrwxrwx 1 101 2013-06-26 02:36 /foo
drwxrwxrwx - 0 2013-06-26 02:43 /home
But then when I try to run an example, the task eventually completes, but I
get " Unable to load libGfarmFSNative library" errors. Looking at the logs
message it seems to be a path problem, but I have tried almost everything
and it doesn't work.
The way I'm setting the path now is writing on conf/hadoop-env.sh the
following line:
export LD_LIBRARY_PATH=/data/local3/marilia/gfarm/lib
I have even moved all the .so files to the hadoop directory, but I still
get the same message...
Any ideas?
Thanks in advance.
