Hi,

I tried to setup the hadoop-cluster using hadoop-0.20.2 and it seem's to be
ok, but when I tried to used another version of hadoop, such as
hadoop-0.20.3, when I start-all.sh, it gaves me an error like this :

uvm12dk: Unrecognized option: -jvm
uvm12dk: Could not create the Java virtual machine.

How to handle with this problem?

Thanks.

Hi,
you should add the libjvm.so path to the LD_LIBRARY_PATH
export LD_LIBRARY_PATH=$JAVA_HOME/jre/lib/$OS_ARCH/server

Hi 臧冬松,

thanks for your answer, I have already add
export LD_LIBRARY_PATH=$JAVA_HOME/jre/lib/$OS_ARCH/server

inside hadoop-env.sh, but it still gave me the same error.

Thanks.

This may not help with your problem, but you might note the Hacker News thread
   http://news.ycombinator.com/item?id=3383228
and the Mongo Hadoop integration github, which you probably have accessed already

Try starting your cluster as a non-root user.
