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-
Which Java's version are you using?
# java -version
java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Java HotSpot(TM) 64-Bit Server VM (build 16.3-b01,
mixed mode)
It worked with hadoop-0.20.2.
Anh-
How do you are starting the services? using
bin/start-all.sh o simply the datanode?
Anh, test first that this option (-jvm is included in that
Java version).
Tested earlier:
# java -jvm
Unrecognized option: -jvm
Could not create the Java virtual machine.
Did you check the requirements for that release? I don´t 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.
