    Description

      The pretty printer could do a better job with metadata. For example:

      ...
Fileinfo:
    BULKLOAD_SOURCE_TASK = attempt_201301272014_0001_r_000000_0
    BULKLOAD_TIMESTAMP = \x00\x00\x01<\x7FcG\x8E
    DELETE_FAMILY_COUNT = \x00\x00\x00\x00\x00\x00\x00\x00
    EARLIEST_PUT_TS = \x00\x00\x01<\x7Fc&F
    EXCLUDE_FROM_MINOR_COMPACTION = \x00
    KEY_VALUE_VERSION = \x00\x00\x00\x01
    MAJOR_COMPACTION_KEY = \xFF
    MAX_MEMSTORE_TS_KEY = \x00\x00\x00\x00\x00\x00\x00\x00
    TIMERANGE = 1359346869830....1359346869830
    hfile.AVG_KEY_LEN = 19
    hfile.AVG_VALUE_LEN = 2
    hfile.LASTKEY = \x00\x04row9\x01dc2\x00\x00\x01<\x7Fc&F\x04
...

      May of these fields could be cleaned up to print in human-readable values.
