----------------------------------
Summary: Agent can become stuck in (re-)registering state during
upgrades
Key: MESOS-8341
URL: https://issues.apache.org/jira/browse/MESOS-8341
Project: Mesos
Issue Type: Bug
Reporter: Benno Evers
Currently, an agent will not be erased from the set of currently
(re-)registering agents if
- it tries to (re-)register with a malformed version string
- it tries to (re-)register with a version smaller than the minimum supported
version
- it tries to (re-)register with a domain when the master has no domain
configured
- the operator marks the slave as gone while the (re-)registration is ongoing
Afterwards, all further (re-)registration attempts with the same agent id will
be discarded, because the master still thinks that the original
(re-)registration is ongoing.
Since most realistic way to encounter this issue would be during cluster
upgrades, and it will fix itself with a master restart, it is unlikely to be
reported externally.
