Kevin Minder updated KNOX-199:
------------------------------
Description:
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 0.96
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",
"col1", "col_value1").now()
The exception produced on the client side is shown below:

When running ExampleHBase.groovy the exception below is produced on the client
side. Also note that the user's guide uses the wrong name from the groovy
script (ExampleHBaseUseCase.groovy vs ExampleHBase.groovy)
