16:10 Ticket #2328 (Improve handling of batchruns in Hive Job Manager) created by ascheibe
13:20 Changeset [12040] by pfleck

Introduced a parameter to adjust the range of layers used for creating a mating pool.

12:52 Changeset [12039] by pfleck

Per-layer parameter can be used to define all multiple layers.
If less values are specified in the array the last value is used for all subsequent layers.
I.e. when the array has the length 1, all layers use that same one value.
From a usability point of view, this behavior may has to be discussed more in detail.
