dlmarion opened a new issue, #4723:
URL: https://github.com/apache/accumulo/issues/4723
**Describe the bug**
`TSERV_SESSION_MAXIDLE` and `TSERV_UPDATE_SESSION_MAXIDLE` are read in the
constructor of `SessionManager`, which is created in the constructor of
`TabletServer` and `ScanServer`. The properties are documented as being zk
mutable, but they will only take affect on a restart.
**Versions (OS, Maven, Java, and others, as appropriate):**
- Affected version(s) of this project: 2.1.x+
**Expected behavior**
SessionManager should respect property updates
**Additional context**
I don't think this is the first time we have encountered a problem like
this. I'm starting to wonder if the AccumuloConfiguration methods that return a
property value should return a Supplier instead. This won't resolve the problem
by itself, but it might get the developer to think about how and where the
property value is retrieved and stored.
