I am seeing some tablets with say 2 million records and some tablets
with 10 million records. I'd like to split the larger tablets so my
mappers all take approximately the same time to run. I'm Ok with
simply cutting the tablet in half. At least for now. I know how to
identify the tablets that I want to split. Is there an existing method
that I can call. I am leery of simply grabbing some code from the
middle of Accumulo and experimenting because I'll probably miss some
nuance causing the system to crash unexpectedly at some future time.

What about the adsplits command in the client API?

Also can use tableOperations().tableIdMap() to convert the table id to
a table name.  Then use the table name to call addSplits()

The issue is that I know the tablet to split, but not the split value.
I think I need something like the findSplitRow method In Tablet.java.
Is that functionality exposed to the client?

if you lower the tables split threshhold, it should cause that function to run
