Michael Shuler updated CASSANDRA-12877:
---------------------------------------
Fix Version/s: 3.10
> SASI index throwing AssertionError on creation/flush
> ----------------------------------------------------
>
> Key: CASSANDRA-12877
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12877
> Project: Cassandra
> Issue Type: Bug
> Components: sasi
> Environment: 3.9 and 3.10 tested on both linux and osx
> Reporter: Voytek Jarnot
> Assignee: Alex Petrov
> Fix For: 3.10
>
>
> Possibly a 3.10 regression? The exact test shown below does not error in 3.9.
> I built and installed a 3.10 snapshot (built 04-Nov-2016) to get around
> CASSANDRA-11670, CASSANDRA-12689, and CASSANDRA-12223 which are holding me
> back when using 3.9.
> Now I'm able to make nodetool flush (or a scheduled flush) produce an
> unhandled error easily with a SASI:
> {code}
> CREATE KEYSPACE vjtest WITH replication = {'class': 'SimpleStrategy',
> 'replication_factor': '1'};
> use vjtest ;
> create table tester(id1 text, id2 text, id3 text, val1 text, primary
> key((id1, id2), id3));
> create custom index tester_idx_val1 on tester(val1) using
> 'org.apache.cassandra.index.sasi.SASIIndex';
> insert into tester(id1,id2,id3, val1) values ('1-1','1-2','1-3','asdf');
> insert into tester(id1,id2,id3, val1) values ('1-1','1-2','2-3','asdf');
> insert into tester(id1,id2,id3, val1) values ('1-1','1-2','3-3','asdf');
> insert into tester(id1,id2,id3, val1) values ('1-1','1-2','4-3','asdf');
> insert into tester(id1,id2,id3, val1) values ('1-1','1-2','5-3','asdf');
> insert into tester(id1,id2,id3, val1) values ('1-1','1-2','6-3','asdf');
> insert into tester(id1,id2,id3, val1) values ('1-1','1-2','7-3','asdf');
> insert into tester(id1,id2,id3, val1) values ('1-1','1-2','8-3','asdf');
> insert into tester(id1,id2,id3, val1) values ('1-1','1-2','9-3','asdf');
> {code}
> Not enough going on here to trigger a flush, so following a manual {{nodetool
> flush vjtest}} I get the following in {{system.log}}:
> {code}
