> The calculation for {{numMachines}} can be too less (causing ArrayIndexOutOfBoundsException)
or too many (causing NPE (HDFS-9958)) if data structures find inconsistent number of corrupt
replicas. This was earlier found related to failed storages. This JIRA tracks a change that
works for all possible cases of inconsistencies.
