> we have lower chance to hit NPE in allocateNodeLocal when run benchmark(hit
> 4 in 20 times).
> Steps:
> 1. setup hadoop 2.2.0 environment
> 2. Run for i in {1..10}; do /hadoop/hadoop-smoke/bin/hadoop jar
> /hadoop/hadoop-smoke/share/hadoop/mapreduce/hadoop-mapreduce-client-common-*.jar
> org.apache.hadoop.fs.TestDFSIO -write -nrFiles 30 -fileSize 64MB; sleep
> 10;done
