Hi,
Can you please add the following to your conf/core-site.xml in Hadoop directory
and try if it solves your problem?
Change "/tmp/hadoop-onur" for yourself.
<property>
<name>hadoop.tmp.dir</name>
<value>/tmp/hadoop-onur</value>
<description>A base for other temporary directories.</description>
</property>
