----------------------------------------
Summary: Master crashes after too many TS re-registrations
Key: KUDU-1933
URL: https://issues.apache.org/jira/browse/KUDU-1933
Project: Kudu
Issue Type: Bug
Components: master
Affects Versions: 1.3.0
Reporter: Jean-Daniel Cryans
I had a cluster with mis-matched versions inside the 1.3 release (something no
one would see using released versions) and ended up with the tablet servers
constantly retrying to register with the master. After a few days of this, the
master died this way:

Ideally the master shouldn't crash, but it also sounds like we're not handling
log_index overflows.
