Application should not fail when hadoop-binaries are missing

[kevinwallimann]

Description

Currently, the application fails when hadoop-binaries are missing, even if scheduler.executors.enableHyperdriveExecutor is set to false, with this error:

Expected behaviour

If scheduler.executors.enableHyperdriveExecutor is set to false, the application should not fail, because in that case the hadoop-binaries are not needed.
