Waiting for [accumulo] balancer to finish

[Mike Drob <ma...@cloudera.com>]

Do we have a programmatic way of asserting that the balancer has finished?
I'm creating tables and pre-splitting them before doing any loads and
currently just sleep for a minute hoping that all of the tablets will be
distributed enough. Is there a better way?

There are some tests in 1.5.x that rely on the GetMasterStats utility to
see if things are balanced. They parse the text output though.

There isn't really a good way.  The test for the faster balancer verifies
that no tablets are offline.
