Problem with running hadoop jar demo.jar in local mode.

[Sheng Guo <en...@gmail.com>]

Hi all,

sorry to bother, I have a simple hadoop job. It was running well both in
local mode and in real hadoop cluster. Recently I try to run it again in
single node cluster, and I got the following error:

$ hadoop-1.0.1/bin/hadoop jar CarDemo.jar

Exception in thread "main" java.io.IOException: Mkdirs failed to create
/tmp/hadoop-sguo/hadoop-unjar6763909861121801460/META-INF/license
at org.apache.hadoop.util.RunJar.unJar(RunJar.java:47)
at org.apache.hadoop.util.RunJar.main(RunJar.java:132)


I tried this both on 0.20.2 and 1.0.0. Both of them exit with exception
like the above.
Can anyone help me on this?

Thanks!!

Sheng

oozie workflow file for teragen and terasort

[Hadoop James <ht...@gmail.com>]

I want to be able to submit my teragen and terasort jobs via oozie.
I have tried different things in workflow.xml to no avail.
Has anybody had any success doing so? Can you share your workflow.xml
file ?

Many thanks

In addition to Harsh answer, configure the tmp hadoop directory, and set
the full permission for the user who is trying to run jar.

[Harsh J <ha...@cloudera.com>]

Your local /tmp directory needs to be writable by your user, for the
"hadoop jar" method to execute properly out of the box.

If that is not possible, edit your conf/core-site.xml to change the
"hadoop.tmp.dir" default of "/tmp/hadoop-${user.name}" to somewhere
that is writable by you, perhaps "${user.home}/tmp" for your user
alone.
