------------------------------------------
Summary: Replication Strategy creation errors are lost in try/catch
Key: CASSANDRA-8909
URL: https://issues.apache.org/jira/browse/CASSANDRA-8909
Project: Cassandra
Issue Type: Improvement
Reporter: Alan Boudreault
Assignee: Alan Boudreault
Priority: Trivial
Fix For: 2.0.13
Attachments: replication-strategy-exception-2.0.patch
I was initially executing a bad cassandra-stress command and was getting this
error:
{code}
Unable to create stress keyspace: Error constructing replication strategy class
{code}
with the following command:
{code}
cassandra-stress -o insert --replication-strategy NetworkTopologyStrategy
--strategy-properties dc1:1,dc2:1 --replication-factor 1
{code}
After digging in the code, I noticed that the error displayed was not the one
thrown by the replication strategy code and that the try/catch block could be
improved. Basically, the Constructor.newInstance can throw an
InvocationTargetException, which provide a better error report.
I think this improvement can also be done in 2.1 (not tested yet). If my
attached patch is acceptable, I will test and provide the right version for 2.1
and trunk.
