Fatal configuration error; unable to start. See log for stacktrace.

What went wrong:
org.cassandraunit.utils.EmbeddedCassandraServerHelper.copy(String, String) copies the file to target/embeddedCassandra/cassandra.yaml because copy strips off all the path information from the from string.

org.cassandraunit.utils.EmbeddedCassandraServerHelper.startEmbeddedCassandra(String, String, long) appends the string as is to build the property to send to cassandra.

Either the copy task needs to be preserve the path passed in, or startEmbeddedCassandra is the one that needs to strip path information.

I've the same issue here

[JosephKiranBabu]

@szetheli @dariodariodario Did you guys find any workaround for this issue?

[prakapenka]

Have same issue by the way.
Seems there is no workaround on it.
When cassandra starts it uses class 'org.apache.cassandra.config.YamlConfigurationLoader' to load yaml file.
Take a look here:
https://github.com/apache/cassandra/blob/4a0d1caa262af3b6f2b6d329e45766b4df845a88/src/java/org/apache/cassandra/config/YamlConfigurationLoader.java#L68

It is reads the

System.getProperty("cassandra.config") 

value that we did previously set when did preparing embedded cassandra.
The issue that we have "cassandra.config" value set as:

file:D:/github/cassandra-unit/cassandra-unit/target/embeddedCassandra/another-cassandra.yaml

cassnadra checks for correct url doing

url.openStream().close(); // catches well-formed but bogus URLs

And sometimes it is treated as correct url sometimes not. If you have a pom-based project and a /target folder will be on classpath - like in cassandra-unit tests in file
https://github.com/jsevellec/cassandra-unit/blob/master/cassandra-unit/src/test/java/org/cassandraunit/CassandraAbstractTestCaseCustomYamlTest.java#L17
that will works. If you have not-maven project that inherits eclipse structure - using test-src forder, doing compilation not in target - this will fail.

To fix this behaviour we just need to set correct "cassandra.config" value which should be like:

file://D:/some/folder/...

That the issue for cassandra-unit.

In general to validate url better to use

UrlValidator urlValidator = new UrlValidator();
Assert.assertTrue( urlValidator.isValid(corectUrlFilePath));

...and only after that attempt to open/close to have final check - that a issue for cassandra.

Since even strictly says incorrect url can be resolved under some circumstances.
I'll try to open pull request on it shortly.

[jsevellec]

hi @prakapenka,

thanks for the investigation. I'm looking forward to the PR ;-)

[yackoa]

Hi @prakapenka do you know if the issue is resolved or if the PR was accepted after the fix ? I am still getting the issue in now

[javadba]

I think i am also seeing this problem but am a new user to cassandra so it may be something else.

[pyjaime]

hey @jsevellec, the problem is still there :)

[jsevellec]

Sorry for the latency...

That should be solved.

While waiting for the next release, snapshot is already available with the fix if you want to give it a try (3.7.1.1-SNAPSHOT : https://oss.sonatype.org/content/repositories/snapshots/)

[jelmerk]

When is this being released?

[samanthakem]

Yeah, when is it going to be released?
