    Description

      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.
