Stefania commented on CASSANDRA-10243:
--------------------------------------
I've removed config reload from GPFS but I've decided to emit an error message
to warn users this is no longer supported in case we detect an updated
configuration file.
I've simplified the liveliness check in the other two remaining snitches as
discussed. I've cleaned-up a bit the code in Gossiper and SS but the legacy
functionality for getting live token owners in SS truncate should be
functionally identical.
I've fixed the [new
dtests|https://github.com/stef1927/cassandra-dtest/commits/10243] according to
the new GPFS error message and noticed that in 2.2 the tests do not pass
because of the missing {{-Dcassandra.ignore_rack}} property. I've therefore
updated them to use the new property name that will be introduced by
CASSANDRA-9474 and marked the tests depending on it. For this reason, I haven't
created a pull request yet.
I've also up-merged, CI is still running:
