bq. This test seems pretty solid and we don't have logs to look into.

for example https://nightlies.apache.org/cassandra/Cassandra-trunk-jvm-dtest/jdk=jdk_1.8_latest,label=cassandra/479/build/test/logs/org.apache.cassandra.distributed.test.NetstatsRepairStreamingTest/
To search in the archives, we can do…
{code}
# webdav mount https://nightlies.apache.org/cassandra/ to /Volumes/cassandra
cd /Volumes/cassandra
xzgrep "name=\"NetstatsRepairStreamingTest\"" Cassandra-trunk/*/TESTS-TestSuites.xml.xz
{code}
shows error (for the class) in builds:
- [Cassandra-trunk#83|https://nightlies.apache.org/cassandra/Cassandra-trunk/83]
- [Cassandra-trunk#108|https://nightlies.apache.org/cassandra/Cassandra-trunk/108]
- [Cassandra-trunk#117|https://nightlies.apache.org/cassandra/Cassandra-trunk/117]
- [Cassandra-trunk#153|https://nightlies.apache.org/cassandra/Cassandra-trunk/153]
- [Cassandra-trunk#161|https://nightlies.apache.org/cassandra/Cassandra-trunk/161]
- [Cassandra-trunk#166|https://nightlies.apache.org/cassandra/Cassandra-trunk/166]
- [Cassandra-trunk#171|https://nightlies.apache.org/cassandra/Cassandra-trunk/171]
- [Cassandra-trunk#195|https://nightlies.apache.org/cassandra/Cassandra-trunk/195]
- [Cassandra-trunk#216|https://nightlies.apache.org/cassandra/Cassandra-trunk/216]
From what I have searched the stage jobs to these failures (i.e. Cassandra-trunk-test builds) are older than the archives we have in nightlies. So only the information in the relevant {{TESTS-TestSuites.xml.xz}} (as linked to above) can be used.
Searching each of those builds reveals the same exception stack trace as described in the ticket description.
For example…
{code}
xzgrep -B1 "error message=\"Table does not match" Cassandra-trunk/216/TESTS-TestSuites.xml.xz
{code}
Summarising, from the archives, from 154 Cassandra-trunk builds there are 9 failures of {{NetstatsRepairStreamingTest.testWithCompressionEnabled}}. That's a flakiness of ~6%, which corresponds to this [history link|jdk=jdk_1.8_latest,label=cassandra/testReport/org.apache.cassandra.distributed.test/NetstatsRepairStreamingTest/testWithCompressionEnabled/history/].
