      Description

      When trying to implement support for tez.runtime.io.sort.mb > 2 GB in pipelinedsorter, I encountered integer overflow exception in ExternalSorter.

      Exception thrown is given below.

      Actual place where the integer overflow happens is in ExternalSorter.getInitialMemoryRequirement()

      int initialMemRequestMb = 
              conf.getInt(
                  TezRuntimeConfiguration.TEZ_RUNTIME_IO_SORT_MB, 
                  TezRuntimeConfiguration.TEZ_RUNTIME_IO_SORT_MB_DEFAULT);
      long reqBytes = initialMemRequestMb << 20;
