mapreduce.LoadIncrementalHFiles hangs..

Last piece of the puzzle!

My Mapreduce succeeded in generating hdfs file, However, bulk load with the
following code:

LoadIncrementalHFiles loader = new LoadIncrementalHFiles(hbaseConf);

loader.doBulkLoad(newExecutionOutput, candidateSendTable);

Just hangs there without any output. I tried to run

hbase org.apache.hadoop.hbase.mapreduce.LoadIncrementalHFiles
<hdfs://storefileoutput> <tablename>

It seems to get into some kind of infinite loop..
