> At present, hdfs oiv tool lacks in verification of input parameter.people can type in
irrelevant option like:
> bq. ./hdfs oiv -i fsimage_0000000000000000000 -p XML -step 1024
> or type in option with wrong format which he think come into effec but actually not:

> bq. ./hdfs oiv -i fsimage_0000000000000000000 -p FileDistribution maxSize 4096 step 512
format
> or some meaningless word which can also get through:
> bq. ./hdfs oiv -i fsimage_0000000000000000000 -p XML Hello Han Meimei
> We'd better not let these cases go unchecked.
