{color:red}Note: patch CANNOT be applied to {{v2.1}} or {{v2.2}}. {color}
For these versions the root exception thrown from CFMetaData and CQL3Type does
not provide any useful information regarding data types, unlike the v3.0 root
exception. Considering this is a minor issue I don't think it's worthwhile
changing those classes to provide a more informative exception - this has
already been taken care of in v3.x.
In v3.0, the root exception is:
{code}
org.apache.cassandra.exceptions.InvalidRequestException: Unknown type
autogeneratedtest.map

org.apache.cassandra.cql3.CQL3Type$Raw$RawUT.prepare(CQL3Type.java:780)

org.apache.cassandra.cql3.statements.CreateTableStatement$RawStatement.prepare(CreateTableStatement.java:225)
at org.apache.cassandra.config.CFMetaData.compile(CFMetaData.java:408)

whereas in v2.1 and v2.2 the root exception is:

> Key: CASSANDRA-10725
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10725
> Project: Cassandra
> Issue Type: Bug
> Components: Tools
> Reporter: Sebastian Estevez
> Assignee: Michael Edge
> Priority: Minor
> Labels: stress, tools
> Fix For: 3.x
>
> Attachments: CASSANDRA-3.0-10725-Cassandra-Stress.patch
>
>
> Steps to reproduce:
> copy the following stress.yaml:
> {code}# Keyspace Name
> keyspace: autogeneratedtest
>
> # The CQL for creating a keyspace (optional if it already exists)
> keyspace_definition: |
> CREATE KEYSPACE autogeneratedtest WITH replication = {'class':
> 'SimpleStrategy', 'replication_factor': 1};
>
> # Table name
> table: smartcity_data
>
> # The CQL for creating a table you wish to stress (optional if it already
> exists)
> table_definition:
> CREATE TABLE smartcity_data (
> device text,
> reporter text,
> time timestamp,
> data_ map,
> metadata_ text,
> solr_query text,
> timeack timestamp,
> timefalse timestamp,
> timeresolved timestamp,
> PRIMARY KEY (device, reporter, time)
> )

> partitions: fixed(1) # Our partition key is the domain so only
> insert one per batch
>
> select: fixed(1)/1000 # We have 1000 posts per domain so 1/1000

> {code}cassandra-stress user profile=stress.yaml ops\(insert=1\) n=10 -rate
> threads=1
> There was a problem parsing the table cql: Unknown keyspace
> autogeneratedtest{code}
> You'll see the following error:
> {quote}
> There was a problem parsing the table cql: Unknown keyspace autogeneratedtest
> {quote}
> The error should instead state:
> {quote}Maps are not currently supported in cassandra-stress{quote}
> If you replace `data_ map`, with `data_ text` it works fine.
