parseResourceConfigValue

                                                     throws AllocationConfigurationException

Parses a resource config value in one of three forms:

1. Percentage: "50%" or "40% memory, 60% cpu"
2. New style resources: "vcores=10, memory-mb=1024" or "vcores=60%, memory-mb=40%"
3. Old style resources: "1024 mb, 10 vcores"

In new style resources, any resource that is not specified will be set to Long.MAX_VALUE or 100%, as appropriate. Also, in the new style resources, units are not allowed. Units are assumed from the resource manager's settings for the resources when the value isn't a percentage.

Parameters:

value - the resource definition to parse

Returns:

a ConfigurableResource that represents the parsed value

Throws:

AllocationConfigurationException - if the raw value is not a valid resource definition

parseResourceConfigValue

public static ConfigurableResource parseResourceConfigValue(java.lang.String value,
                                                            long missing)
                                                     throws AllocationConfigurationException

Parses a resource config value in one of three forms:

1. Percentage: "50%" or "40% memory, 60% cpu"
2. New style resources: "vcores=10, memory-mb=1024" or "vcores=60%, memory-mb=40%"
3. Old style resources: "1024 mb, 10 vcores"

In new style resources, any resource that is not specified will be set to missing or 0%, as appropriate. Also, in the new style resources, units are not allowed. Units are assumed from the resource manager's settings for the resources when the value isn't a percentage. The missing parameter is only used in the case of new style resources without percentages. With new style resources with percentages, any missing resources will be assumed to be 100% because percentages are only used with maximum resource limits.

Parameters:

value - the resource definition to parse

missing - the value to use for any unspecified resources

Returns:

a ConfigurableResource that represents the parsed value

Throws:

AllocationConfigurationException - if the raw value is not a valid resource definition
