> Consider the following scenario: A StreamApplication containing two pipelines with the output StreamDescriptor of the first pipeline being the input StreamDescriptor for the second pipeline. With Samza 1.0 changes, this results in the "Serde for streamId: testavro-SIMPLE1 is already defined. Cannot change it to different serdes." exception. This is an important use-case for Samza-sql. We need to fix this.
> We have an end-to-end test case which is disabled because of this issue: testEndToEndMultiSqlStmtsWithSameSystemStreamAsInputAndOutput
