java.lang.OutOfMemoryError: Java heap space
Hi All,
Can someone help me with the above error. I am using Hadoop 1.0.0. and I tried increasing the HEAP size, using following command, but all in vain.
export HADDOP_HEAP=4000
So far I am using only about 200 mb big data. I want to use few GBs of data later.
Please help
Regards

Hi Puneet:
You can try this at mapreduce config:
<property>
<name>mapred.child.java.opts</name>
<value>-Xmx4000m</value>
</property>
Cheers
