Allan Yang commented on HBASE-21185:
------------------------------------
{code}
+ op.put("total_size_sum", new Long(cell.getFamilyLength() +
+ cell.getQualifierLength() +
+ cell.getRowLength() +
+ cell.getTagsLength() +
+ cell.getValueLength()));
}
{code}
You forget there is a timestamp in cells which takes 8 bytes. You should used
method in CellUtils class avoiding writing method yourself to make better
encapsulation. For this case, you can use getSumOfCellElementLengths(making it
public first).

> *WALPrettyPrinter* is very useful for troubleshooting wal issues, such as
> faulty replication sinks. An useful information one might want to track is
> the size of a single WAL entry edit, as well as size for each edit cell. Am
> proposing a patch that adds calculations for these two, as well an option to
> seek straight to a given position on the WAL file being analysed.
