Daniel Meyer commented on CASSANDRA-5965:
-
Patch is good. To repro the issue it is important to insert an empty string
into an indexed column. Leaving it null, will not cause a repro.
To repro:
CREATE TABLE cf (
name text PRIMARY KEY,
val1 text,
val2 text
)
CREATE INDEX cf_val2_idx ON cf (val2);
INSERT INTO (name, val1, val2) VALUES ('dmeyer', 'testval', '');
Then run:
nodetool rebuild index ks cf cf.cf_val2_idx
flush
restart node
Observe the ERROR in system.log
After applying the patch and building and reproducing the above procedure the
error did not occur.

I think this is typically caused by indexing empty column, and then the key
in index columnfamily is added to its IndexSummary.
