      Description

      AccumuloInputFormat (and I suspect AccumuloOutputFormat) sends the table name to each mapper. The mapper uses this table name to create a scanner. In the case of the following events a map reduce job could read from two different table ids.

      1. start M/R job reading table A
      2. rename table A (tableId=1) to table C
      3. rename table B (tableId=2) to table A

      If the input format passed table id 1 to the mappers, then the renames would not cause a problem.
