ci-cassandra's [test page for 
CASTest|https://ci-cassandra.apache.org/job/Cassandra-trunk-jvm-dtest/lastCompletedBuild/jdk=jdk_1.8_latest,label=cassandra/testReport/org.apache.cassandra.distributed.test/CASTest/]
 is reporting flakiness at 37%.

h4. Searching nightlies.a.o

The logs for this test are archived at
{noformat}
https://nightlies.apache.org/cassandra/Cassandra-trunk-jvm-dtest/jdk=jdk_1.8_latest,label=cassandra/*/build/test/logs/org.apache.cassandra.distributed.test.CASTest/
{noformat}
for example, the following are the logs for the {{incompletePropose}} failures…
- 
https://nightlies.apache.org/cassandra/Cassandra-trunk-jvm-dtest/jdk=jdk_1.8_latest,label=cassandra/478/build/test/logs/org.apache.cassandra.distributed.test.CASTest/
- 
https://nightlies.apache.org/cassandra/Cassandra-trunk-jvm-dtest/jdk=jdk_1.8_latest,label=cassandra/476/build/test/logs/org.apache.cassandra.distributed.test.CASTest/

To search in the archives, we can do**…
{code}
# webdav mount https://nightlies.apache.org/cassandra/ to /Volumes/cassandra
cd /Volumes/cassandra

xzgrep "name=\"CASTest\"" Cassandra-trunk/*/TESTS-TestSuites.xml.xz
{code}
shows error (for the class) in builds:
- 
[Cassandra-trunk#197|https://nightlies.apache.org/cassandra/Cassandra-trunk/197]
- 
[Cassandra-trunk#202|https://nightlies.apache.org/cassandra/Cassandra-trunk/202]
- 
[Cassandra-trunk#212|https://nightlies.apache.org/cassandra/Cassandra-trunk/212]

Note, these are other test failures than {{incompletePropose}}.


**) The test xml for the jvm-dtest jobs, like 
[this|https://ci-cassandra.apache.org//job/Cassandra-trunk-jvm-dtest/jdk=jdk_1.8_latest,label=cassandra/lastSuccessfulBuild/artifact/build/test/output/],
 are not archived (yet) so the slower greps against the full pipeline xml test 
reports have to done.
