Subject [jira] [Commented] (CASSANDRA-9915) IndexError('list index out of range') when trying to connect to Cassandra cluster with cqlsh
Date Wed, 05 Aug 2015 15:04:04 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-9915?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14658331#comment-14658331
] 

Adam Holmberg commented on CASSANDRA-9915:
------------------------------------------

The driver is definitely having problems with the {{healthcheck.testdyna}} table, which has
a comparator of {{DynamicCompositeType()}} (with no subtypes). The driver was written assuming
composite types should always have subtypes. *[~prabir_apache] do you know how this table
was created?* I'm trying to figure out if this is valid metadata that should be handled, or
if something has gone wrong on the server side.

In any case, I created this ticket to make the driver more robust against these unexpected
metadata states.

In the mean time, if you are not using that table you can resolve this by dropping it via
JDBC.
