Wellington Chevreuil updated HBASE-21185:
-----------------------------------------
Release Note:
This adds two extra features to WALPrettyPrinter tool:
1) Output for each cell combined size of cell descriptors, plus the cell value
itself, in a given WAL edit. This is printed on the results as "cell total size
sum:" info by default;
2) An optional -g/--goto argument, that allows to seek straight to that
specific WAL file position, then sequentially reading the WAL from that point
towards its end;
> WALPrettyPrinter: Additional useful info to be printed by wal printer tool,
> for debugability purposes

> *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.
