Subject [jira] [Commented] (SYSTEMML-453) JMLC in Standalone mode and dependency on Hadoop
Date Wed, 14 Jun 2017 05:03:00 GMT


Matthias Boehm commented on SYSTEMML-453:

Thanks @deron for taking this over - I linked the current placeholders for this task. If possible
let's retain MatrixBlock as the writable and introduce a base class without the dependency
which holds the actual operations. This is important because use MatrixBlock as the value
in our binary representation which is based on sequence files - changing the class name would
render any binary data unreadable.

> Hello,
> I am using the JMLC API in standalone mode. But Instantiating org.apache.sysml.api.jmlc.Connection
fails with NoClassDefFoundError: org/apache/hadoop/conf/Configuration.
