Jaeger-cassandra-schema compatibility with cassandra

[princeop]

Using jaeger-cassandra-schema docker with cassandra 3.0.12 causes this exception

<stdin>:156:ConfigurationException: Unable to find custom indexer class 'org.apache.cassandra.index.sasi.SASIIndex' on this line:

CREATE CUSTOM INDEX ON ${keyspace}.dependencies (ts_index) USING 'org.apache.cassandra.index.sasi.SASIIndex' WITH OPTIONS = {'mode': 'SPARSE'};

This in turn causes to dependency functionality not working on jaeger-query docker:

"Cannot execute this query as it might involve data filtering and thus may have unpredictable performance. If you want to execute this query despite the performance unpredictability, use ALLOW FILTERING"

SASIIndex in available in cassandra since version 3.4+

Thanks for catching this, we removed SASI indexes but forgot to do it for the dependencies table, we'll get rid of it.

Any update on this?

[black-adder]

It's a breaking change as of this moment so we're gonna cut a release and then fix it for the upcoming release

[jpkrohling]

This should have been fixed by #278 .

[yurishkuro]

@jpkrohling it won't be - the request in this issue is to support older versions of Cassandra, specifically pre-3.4 when SASI indices were not available. The Dependencies table is the only one still using a SASI index.

Any updates on this fix?

[yurishkuro]

I expect it to happen within a month.

[jpkrohling]

Took a bit more than a month, but I think this is now fixed :-)
