> In setupLocalDiskFetch() method[this is invoked when the fetcher is in the
> same host as the target map host], first try to check if we can open the
> target spill file using the localDirAllocator.getLocalPathToRead(). The
> localDirAllocator searches through the list of configured dirs for the file.
> In disk full scenarios, if the path is not found, fetcher should to try an
> http fetch.
> proposed solution:
> in local fetch mode, the fetcher should first try getLocalPathToRead() for
> all the pending maps. and So local fetch gets divided into 2 stages: first
> the maps for which path was found via LocalDirAllocator and second construct
> a http fallback fetch list for the maps which couldnt be found via
> LocalDirAllocator.getLocalPathToRead() and do an http fetch.
