---------------------------------------------
Branch
[sasi_validation|https://github.com/xedin/cassandra/tree/sasi_validation]
addresses this making sure that unknown mode exceptions are re-thrown as
ConfigurationException.
> [SASI Pre-QA] Index mode validation throws exception but do not cleanup index

> {code:sql}
> CREATE KEYSPACE music WITH replication = {'class': 'SimpleStrategy',
> 'replication_factor': '1'} AND durable_writes = true;
> CREATE TABLE music.albums (
> id int PRIMARY KEY,
> title text
> );
> cqlsh:music> CREATE CUSTOM INDEX IF NOT EXISTS ON music.albums(title) USING
> 'org.apache.cassandra.index.sasi.SASIIndex' WITH OPTIONS = { 'mode':'NORMAL'};
> ServerError: <ErrorMessage code=0000 [Server error]
> message="java.lang.RuntimeException: java.util.concurrent.ExecutionException:
> java.lang.RuntimeException: java.lang.reflect.InvocationTargetException">
> {code}
> The error message is useless, by looking into the
> /var/log/cassandra/system.log message, the true error message is:
> *Caused by: java.lang.IllegalArgumentException: No enum constant
> org.apache.cassandra.index.sasi.disk.OnDiskIndexBuilder.Mode.NORMAL*
> *at java.lang.Enum.valueOf(Enum.java:238) ~[na:1.8.0_45]*
> But worse, even the index creation fails, its metadata is not cleaned up so
> that further attempt to create an index on the same column using the correct
> mode also fails:
> {code:sql}
> cqlsh:music> CREATE CUSTOM INDEX IF NOT EXISTS ON music.albums(title) USING
> 'org.apache.cassandra.index.sasi.SASIIndex' WITH OPTIONS = { 'mode':'PREFIX'};
> ServerError: <ErrorMessage code=0000 [Server error]
> message="java.lang.RuntimeException: java.util.concurrent.ExecutionException:
> java.lang.RuntimeException: java.lang.reflect.InvocationTargetException">
> {code}
> The only word-around is to drop the index. The index is not displayed by
> *DESCRIBE TABLE albums*. It only appears in the *system_schema.indexes*
> table...
