Hi all,
I am trying to install Hadoop (release 0.20.203) on a machine with CentOS.
When I try to start HDFS, I get the following error.
: Unrecognized option: -jvm
: Could not create the Java virtual machine.
Any idea what might be the problem?
Thanks,
Abhishek

Hi all,
I just restarted my cluster and now the namenode is not starting up. I get the
following error:
10/07/22 09:14:40 INFO namenode.NameNode: STARTUP_MSG:

actually you can put the hadoop.tmp.dir to other place, e.g /opt/hadoop_tmp
or /var/hadoop_tmp. first create the folder there, and assign the correct
mode for the hadoop_tmp folder, (chmod 777 for all the user to use hadoop).
then change the conf xml file accordingly, and run "hadoop namenode
-form
The property you are going to need to set is
dfs.name.dir
${hadoop.tmp.dir}/dfs/name
Determines where on the local filesystem the DFS name node
should store the name table. If this is a comma-delimited list
of directories then the name table is replicated in all of the
di
which configuration file?

Maybe first time you are starting as user hadoop, now this time you
are starting as user root.
Or as stated above something is cleaning out your /tmp. Use your
configuration files to have namenode write to a permanent place.

I am seeing following error in my NameNode log file.

x27;m going to take a guess at your issue here and say that you used the
/tmp as a path for some of your hadoop conf settings and you have rebooted
lately. The /tmp dir is wiped out on reboot.

Does anyone have solution to this issue?
