In case compression is being used, these counters will represent the compressed data sizes. The uncompressed size will not be available. This is not a direct back-port of 5710. (Counters will be computed in MapTask instead of in individual RecordReaders). 0.20.100 -> New API -> MAP_INPUT_BYTES will be computed using this method Old API -> MAP_INPUT_BYTES will remain unchanged. 0.23 -> New API -> MAP_INPUT_BYTES will be computed using this method Old API -> MAP_INPUT_BYTES likely to use this method -- This message is automatically generated by JIRA.
