> taskmanager.sh will print the following message when starting the cluster if bc is not
installed and off-heap memory is enabled and configured as a ratio. The script should first
check that bc is installed and otherwise print a specific message.

> [ERROR] Configured TaskManager managed memory fraction is not a valid value. Please set
'taskmanager.memory.fraction' in flink-conf.yaml
> {noformat}
> An example of a distribution where bc is not installed by default are the Debian images
