FAQ
I am having an issue starting a job on a hadoop pseudo cluster. I am getting an exception see below. I tried to override the mapred.local.dir with -D parameter and by passing a custom config as well

Here is the custom config declaration:

zeltoa01@hadoop01:~/dev/etl/Hadoop/ybhadoop$ cat etc/hadoop-cluster.xml
<?xml version="1.0"?>
<configuration>
<property>
<name>mapred.local.dir</name>
<value>${hadoop.tmp.dir}/mapred/local</value>
</property>
<property>
<name>hadoop.tmp.dir</name>
<value>/opt/hadoop-datastore</value>
<description>A base for other temporary directories.</description>
</property>
