Description

At present, hdfs oiv tool lacks in verification of input parameter.people can type in irrelevant option like:

./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:

./hdfs oiv -i fsimage_0000000000000000000 -p FileDistribution maxSize 4096 step 512 format

or some meaningless word which can also get through:

./hdfs oiv -i fsimage_0000000000000000000 -p XML Hello Han Meimei

We'd better not let these cases go unchecked.
