Release Notes:Bug Fix
Description
When using the hiera() function with a second parameter of undef, Hiera returns the empty string for the value. When using Puppet 3.7 future parser, this means that Hiera returns a truthy value when it cannot find a key.
In the Puppet 3 language, this doesn't matter because '' == undef evaluates to true.
A workaround for this is to specify a second parameter of false instead of undef, but that doesn't make this behavior any less confusing.
Final resolution: In the Puppet 4 language, the hiera functions will now respect and return a default of undef, same as they do in the Puppet 3 language. (in comment)
risk assessment: high
probability: high (regression)
severity: medium (can work around in puppet code, but it's not-expected)
highest test layer: acceptance
FR only for now (acceptance is ticketed in a larger test for all functions) PUP-4342
