----------------------------------------------

[~sandeep.pal] When you get a chance, can you create a PR for branch-1/2? There are conflicts when cherry-picking. I don't mind fixing them but I don't have the setup for testing the changes. Given you already have that setup, it is probably easier for you fix and test them.

> Currently, [WALPrettyPrinter|https://github.com/apache/hbase/blob/master/hbase-server/src/main/java/org/apache/hadoop/hbase/wal/WALPrettyPrinter.java] provides an option to ignore the values in the output, but it prints the whole cell and has no option to ignore some information from the cell. Sometimes, the user may only need the row keys from WAL and it may reduce the size of output from WALPrettyPrinter significantly. 
> We should provide flexibility to output only rowkey from the cell. 
> In addition we should increase the flexibility for providing multiple tables in the table filter.
