Project: Hadoop HDFS
Issue Type: Bug
Components: tools

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.
