> After this particular BPOfferService is down during the run time.
> And this particular NN will not have the details of this DN
> Similar issues are discussed in the following JIRAs
> https://issues.apache.org/jira/browse/HDFS-2882
> https://issues.apache.org/jira/browse/HDFS-7714
> Can we retry in this case also with a larger interval instead of shutting
> down this BPOfferService ?
> I think since this exceptions can occur randomly in DN it is not good to keep
> the DN running where some NN does not have the info !
