Subject [jira] [Created] (HBASE-7690) Improve metadata printing in HFilePrettyPrinter
Date Mon, 28 Jan 2013 05:05:13 GMT
Nick Dimiduk created HBASE-7690:
-----------------------------------

             Summary: Improve metadata printing in HFilePrettyPrinter
                 Key: HBASE-7690
                 URL: https://issues.apache.org/jira/browse/HBASE-7690
             Project: HBase
          Issue Type: Improvement
          Components: HFile
            Reporter: Nick Dimiduk
            Assignee: Nick Dimiduk
            Priority: Minor


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

{pre}
...
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
...
{pre}

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