Low Description
I use a set type in table like sample, but if awkward cql statement failed, cqlsh is not worked like belows.
serkeyspace> CREATE TABLE images (
... name text PRIMARY KEY,
... owner text,
... date timestamp,
... tags set<text>
... );
cqlsh:userkeyspace> delete tags['cuddly'] from images where name = 'cat.jpg'; // not allowd cql statement
(hang)
^C
cqlsh:userkeyspace> select * from plays;
(hang)
^C
cqlsh:userkeyspace> describe table plays;
(hang)
^C
cqlsh:userkeyspace> quit
---------------------------------
cassandra log when hang is occured.
