Subject [jira] [Issue Comment Deleted] (CASSANDRA-12877) SASI index throwing AssertionError on index creation
Date Sat, 05 Nov 2016 03:21:58 GMT

]

Voytek Jarnot updated CASSANDRA-12877:
--------------------------------------
    Comment: was deleted

(was: Attached (slightly sanitized) result of a failed attempt to create a SASI index as described
but on my localhost 1-machine cluster.  Full series of stacktraces as well as the "Update
table ..." output, giving the details of my setup.

Perhaps worth mentioning: the tables has ~27 million values for the final primary key column.)

>                 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

> Possibly a 3.10 regression?
> I built and installed a 3.10 snapshot (built 03-Nov-2016) to get around CASSANDRA-11670,
CASSANDRA-12689, and CASSANDRA-12223 which are holding me back when using 3.9.
> Would like to state up front that I can't duplicate this with a lightweight throwaway
test, which is frustrating, but it keeps hitting me on our dev cluster.  It may require a
certain amount of data present (or perhaps a high number of nulls in the indexed column) -
never had any luck duplicating with the table shown below.
> Table roughly resembles the following, with many more 'valx' columns:
> CREATE TABLE idx_test_table (
>     id1 text,
>     id2 text,
>     id3 text,
>     id4 text,
>     val1 text,
>     val2 text,
>     PRIMARY KEY ((id1, id2), id3, id4)
> ) WITH CLUSTERING ORDER BY (id3 DESC, id4 ASC);
> CREATE CUSTOM INDEX idx_test_index ON idx_test_table (val2) USING 'org.apache.cassandra.index.sasi.SASIIndex';
> The error below occurs in 3.10, but not in 3.9; it occurs whether I insert a bunch of
dev data and then create the index, or whether I create the index and then insert a bunch
of test data.
