There is no data value information in HLog?
Hello,

I used the $ ./bin/hbase org.apache.hadoop.hbase.regionserver.wal.HLog
--dump command to check the HLog information. But I can not find any
data information. The output of my HLog file is looks like follows:

Sequence 933 from region 85986149309dff24ecf7be4873136f15 in table test
  Action:
    row: Udo
    column: Course:Computer
    at time: Mon Mar 19 14:09:29 CET 2012

Sequence 935 from region 85986149309dff24ecf7be4873136f15 in table test
  Action:
    row: Udo
    column: Course:Math
    at time: Mon Mar 19 14:09:29 CET 2012

The functionality of HLog is for recovery. But without data value
information, how can hbase use the information in HLog to do recovery.
My hbase version is 0.92.0.

Regards!
