Subject [jira] [Commented] (CASSANDRA-16104) Wrong warning about data volumes capacity
Date Thu, 15 Jul 2021 12:55:00 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-16104?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17381330#comment-17381330
] 

Andres de la Peña commented on CASSANDRA-16104:
-----------------------------------------------

I think that we can change the value of {{concurrent_compactors}} without the setters, we
can just edit it in the configuration file of each tested node. The idea for the test would
be verifying that nodetool is able to throw the warning depending on the configuration of
the connected node, independently of the local environment. I gave it a try with [this tiny
Python dtest|https://github.com/apache/cassandra-dtest/pull/150]. The test passes with the
patch and fails without it.

Here is a new CI round including 100 rounds of the proposed dtest:
