All,
I'm having an issue but I'm probably missing something simple. I am specifying
a custom encoder for the SummingArrayCombiner but during unit testing (using
MockInstance) it cannot find the class in my local project?
The code is below:
MockInstance instance = new MockInstance();
accumulo = instance.getConnector("user", new PasswordToken("password"));
assertTrue(accumulo.instanceOperations().testClassLoad(FixedLengthLongArrayEncoder.class.getName(),
FixedLengthLongArrayEncoder.class.getTypeName()));
The test fails due to:
java.lang.ClassNotFoundException: IO Error loading class

Any ideas on what I'm doing wrong? For remote testing I'm aware I need to
include the JAR in Accumulo's classpath, but how is this achieved in local unit
tests?
Many thanks,
Michael
