Description

Most of Samza's logging and output uses the style:

warn("Some error for %s happened." format (myVar))

This style is actually really problematic because it leads to runtime exceptions in cases where there is an extra %s or there was a %d when it should have been a %s.

I think we should switch everything over to the standard Java style:

warn("Some error for " + myVar + " happened.")
