In various embodiments, a data integration system is disclosed which enables users to debug distributed data integration scenarios which are platform and technology independent. A debugger client can connect to a plurality of local and/or remote hosts executing portions of a distributed data integration scenario. The debugger client can additionally enable line-by-line debugging of the portions of the distributed data integration scenario using a plurality of language-specific interfaces. The language-specific interfaces can further enable the user to dynamically update and debug changes to the code during debugging, reducing the time and resources required by multiple recompilations of the code.
