      Description

      The exception handling in nextKeyValueTolerateCorruptions treats IOException as follows:

      • if EOFException, corrupt, can be tolerated
      • If CheckSumException, corrupt, can be tolerated
      • else not a corruption, re-throw

      But the compression code can also throw IOException in case of corruption, which will get re-thrown in this case.

      The correct way of handling IOException is:

      • if BlockMissingException, re-throw.
      • if not BlockMissingException -> corruption, can be tolerated
