> Add an option (count-delete-markers) to the
> [RowCounter|https://github.com/apache/hbase/blob/8a9ad0736621fa1b00b5ae90529ca6065f88c67f/hbase-mapreduce/src/main/java/org/apache/hadoop/hbase/mapreduce/RowCounter.java#L240C62-L240C75]
> tool to count the number of Delete Markers of all types, i.e. (DELETE,
> DELETE_COLUMN, DELETE_FAMILY,DELETE_FAMILY_VERSION)
> We already have such a feature within our internal implementation of
> RowCounter and it's very useful.
> Implementation Ideas:
> 1. If the option is passed, initialize the empty job counters for all 4 types
> of deletes.
> 2. Within mapper, increase the respective delete counts while processing each
> row.
