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
