Just to clarify: compactions don't implicitly change the table
"distribution". The number and/or boundaries of tablets don't change as
a part of a compaction.

Just a thought, will forcing a major compaction take care of this?
Merging smaller tablets and deleting empty ones?

*UNOFFICIAL*
I have a table that has evolved to have 1.07T tablets and I fairly
confident a large portion of these are now empty or very small. I'd
like to merge smaller tablets and delete empty tablets, is there a
smart way to do this?
My thought was to query the metadata table for all tablets under a
certain size for the table and thenmerge these tablets.
Is the first number in thevalue the size of the tablet, ie
> scan -b 1xk -e 1xk\xff -c file
1xk;34234 file:hdfs//name/accumulo/tables/1xk/t-er23423/M423432.rf
[] *213134*,234234
Also, are there any side effects of this that I need to be aware of
when doing this on a massive table?
Thanks in advance,
Matt
