I think we should get rid of both Merge and HMerge.
We should not have any tool which will work in offline mode by going over
the HDFS data. Seems very brittle to be broken when things get changed.
Only use case I can think of is that somehow you end up
bq. HMerge can merge multiple regions by going over the list of
regions and checking
their sizes.
bq. But both of these tools (Merge and HMerge) are very dangerous
I came across HMerge and it looks like dead code. Isn't referenced from
anywhere except one test. (This is what lars also pointed out
Merge has very limited usability singe it can do a single merge and can
only run when HBase is offline.
HMerge can merge multiple regions by going over the list of regions and
checking their sizes.
And of course we have the "supported" online merge which is the shell
command.
Deprecating HMerge is fine.

Hey,
Sorry to resurrect this old thread, but working on the book update, I
came across the same today, i.e. we have Merge and HMerge. I tried and
Merge works fine now. It is also the only one of the two flagged as
being a tool. Should HMerge be removed? At least deprecated?

HMerge can merge regions of tables that are disabled. It also merges all
that qualify, i.e. where the merged region is less than or equal of half the
configured max file size.
Merge on the other hand does have a main(), so can be invoked:
$ hbase org.apache.hadoop.hbase.util.Merge
Usage: bin
()
functions...
and no one does that but the unit test. But it would be good to have
this on
the CLI and shell as a command (and in the shell maybe with a
confirmation
message?), but it is not available AFAIK.
