Java Heapsize Error in MapReduce Program to upload Data into HBase

I have 500 MB tsv file which contains 3 lakh lines(tuples). I have map reduce program in which Hbase Java APIs are used to insert lines(tuples) to HBase Table. It generates Heap size error exception during running. How can tackle this error ? I have increased memory size in configuration but it does not work. Can any one help ?


Usually you run out of heap space when an in-memory collection of some kind got too big. There's not enough information in the question to provide a specific answer though. Can you provide any more details?
