[jira] [Commented] (CASSANDRA-4744) Non-escaped single quotes causes CQL to hang

My application just pauses indefinitely. Do you have a recommendation to work around this problem? Even the cqlsh utility does not handle this condition gracefully.

This behavior is inherited by clients implementing execute_cql. The end result is a client application that stops responding. For example, the following is entered in cqlsh (notice the ellipses): cqlsh:Keyspace1 INSERT INTO Test1 (testId, test1) VALUES (1566bb5d-9093-4abd-bcaa-e1ac90b94a47, 'This is a test with Cassandra's reserved characters') USING CONSISTENCY LOCAL_QUORUM; ...

The problem is, a client that implemented execute_cql cannot recover from this. My application just pauses indefinitely. Do you have a precise example? Because I'm not able to reproduce that part (I get a Bad Request: line 1:72 mismatched character 'EOF' expecting ''' right away, which describe correctly the problem). To be clear, I'm not contesting that cqlsh does that (have you tried a ctrld-D to complete the input?).
