> Dear Gora developers
> In recent got repositiry, I've found the following lines in gora-cassandra/src/main/java/org/apache/gora/cassandra/store/CassandraClient.java.
> <pre>
> String opConsisLvl = (readOpConsLvl!=null || !readOpConsLvl.isEmpty())?readOpConsLvl:DEFAULT_HECTOR_CONSIS_LEVEL;
>       ccl.setDefaultReadConsistencyLevel(HConsistencyLevel.valueOf(opConsisLvl));
>       LOG.debug("Hector read consistency configured to '" + opConsisLvl + "'.");
>       opConsisLvl = (writeOpConsLvl!=null || !writeOpConsLvl.isEmpty())?writeOpConsLvl:DEFAULT_HECTOR_CONSIS_LEVEL;
> </pre>
> It seems readOpConsLvl or writeOpConsLvl is null, there could be NullPointerException
as the comparison operator is "||" rather using "&&". I have no idea if this is an
actual bug but just reporting. Thanks!
