> Extend OIV to detect FSImage corruption

>
> A follow-up Jira for HDFS-13031: an improvement of the OIV is suggested for
> detecting corruptions like HDFS-13101 in an offline way.
> The reasoning is the following. Apart from a NN startup throwing the error,
> there is nothing in the customer's hand that could reassure him/her that the
> FSImages is good or corrupted.
> Although real full checking of the FSImage is only possible by the NN, for
> stack traces associated with the observed corruption cases the solution of
> putting up a tertiary NN is a little bit of overkill. The OIV would be a
> handy choice, already having functionality like loading the fsimage and
> constructing the folder structure, we just have to add the option of
> detecting the null INodes. For e.g. the Delimited OIV processor can already
> use in disk MetadataMap, which reduces memory consumption. Also there may be
> a window for parallelizing: iterating through INodes for e.g. could be done
> distributed, increasing efficiency, and we wouldn't need a high mem-high CPU
> setup for just checking the FSImage.
> The suggestion is to add a --detectCorruption option to the OIV which would
> check the FSImage for consistency.
