Starting Datanode

Anh Nguyen 2011-05-20, 17:32

Hi,

I just upgraded to hadoop-0.20.203.0, and am having problem starting the
datanode:
# hadoop datanode
Unrecognized option: -jvm
Could not create the Java virtual machine.

It looks like it has something to do with daemon.sh, particularly the
setting of HADOOP_OPTS:
   if [[ $EUID -eq 0 ]]; then
   HADOOP_OPTS="$HADOOP_OPTS -jvm server $HADOOP_DATANODE_OPTS"
   else
   HADOOP_OPTS="$HADOOP_OPTS -server $HADOOP_DATANODE_OPTS"
   fi

Am I missing something?

Thanks in advance.

Anh-

It worked with hadoop-0.20.2.

How do you are starting the services? using bin/start-all.sh o simply
the datanode?

Did you check the requirements for that release? I donï¿½t know if this
version require at least a mayor version to 1.6.20.
Did you test with the 1.6.24?

I think that can be a bug.
Take a time to review the last issues for Hadoop on the JIRA of the project.
