> When running the samples/ExampleHBase.groovy Knox Client DSL script, an
> exception is produced on the client side. This is due to an incompatibility
> between Knox 0.3.0 Client DSL and a change in HBase 0.96. The result is that
> the Knox Client DSL cannot be used to access HBase operations that involve
> empty column qualifiers. This only affects the Knox Client DSL. The HBase
> REST API can still be used via the Knox Gateway for both HBase 0.95 and 0.96.
> // This Client DSL command will fail with Knox 0.3.0 Client DSL and HBase
> 0.96. It will work with HBase 0.95.
> HBase.session(session).table("table1").row("row_id_1").store().column("family1",
> null, "fam_value1").now()
> // It may also be possible in some cases to work around this problem by
> adding an extra ":" to the column family parameter
> HBase.session(session).table("table1").row("row_id_1").store().column("family1:",
> null, "fam_value1").now()
>
> // This Client DSL command will work with both HBase 0.95 and HBase 0.96.
> HBase.session(session).table("table1").row("row_id_1").store().column("family1",
