The rationale behind this class is to compare two YARN application ID `String`s, when the cluster startup time is different. Newer application IDs will be treated as "greater". We cannot really use plain `String` comparison because we could face situations where different application IDs are read with different cluster startup times. - András ----------------------------------------------------------- This is an automatically generated e-mail.
