Harsh J updated MAPREDUCE-4172: ------------------------------- Description: There are lots of warnings in the hadoop-mapreduce-project presently. We can clear almost all of this away: * Unused imports * Unused variables ** For loops that can be replaced with while instead to save an unused variable * Unused methods * Deprecation warnings where an alternative can be used (Especially SequenceFile reader/writer usage and MiniDFSCluster usage) * Deprecation warnings where an alternative isn't clear (Especially MiniMRCluster usage and DistributedCache API usage where a Job object may not be available) * Unchecked conversions * Raw type usage * (etc.) I'm going to open one sub-task per sub-project we have, with patches attached to them. was: There are lots of warnings (unused imports, unused variables, for loops that can be replaced with while instead to save a variable, unused methods, deprecation warnings where an alternative isn't clear, unchecked calls, raw types, etc.) in the hadoop-mapreduce-project presently.
