> Project: Cassandra
> Issue Type: Sub-task
> Reporter: Eduardo Aguinaga
> Priority: Trivial
> Fix For: 3.0.10, 3.10
>

>
> Overview:
> In May through June of 2016 a static analysis was performed on version 3.0.5
> of the Cassandra source code. The analysis included an automated analysis
> using HP Fortify v4.21 SCA and a manual analysis utilizing SciTools
> Understand v4. The results of that analysis includes the issue below.
> Issue:
> In the file CqlRecordWriter.java on line 128 there is a portability problem
> with the call to toLowerCase() because it has different locales which may
> lead to unexpected output. This may also circumvent custom validation
> routines.
> {code:java}
> CqlRecordWriter.java, lines 127-130:
> 127 String cqlQuery = CqlConfigHelper.getOutputCql(conf).trim();
> 128 if (cqlQuery.toLowerCase().startsWith("insert"))
> 129 throw new UnsupportedOperationException("INSERT with CqlRecordWriter
> is not supported, please use UPDATE/DELETE statement");
> 130 cql = appendKeyWhereClauses(cqlQuery);
> {code}
