Josh Elser created ACCUMULO-4410:
------------------------------------
Summary: Master didn't not resume balancing after administrative
tserver shutdown
Key: ACCUMULO-4410
URL: https://issues.apache.org/jira/browse/ACCUMULO-4410
Project: Accumulo
Issue Type: Bug
Components: master
Affects Versions: 1.8.0
Reporter: Josh Elser
Priority: Critical
I realized that I misconfigured a property, so, I started manually stopping
each tabletserver (using {{accumulo admin stop <host:port>}}).
This worked as intended, the tablets were migrated and the tserver was stopped:

However, after this point, the master did not resume balancing:

Even after I brought a new tserver online on that host, the master still did
not resume balancing:
