Params and ParamInfo class
[ https://issues.apache.org/jira/browse/FLINK-12881?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Xu Yang updated FLINK-12881:
----------------------------
Description:
* change Params$get to support aliases
support aliases
if the Params contains the specific parameter and alias, but has more than one value or
if the Params doesn't contains the specific parameter, while the ParamInfo is optional but has no default value
when isOptional is true, contain(ParamInfo) is true, it will return the value found in Params, whether the value is null or not. when isOptional is true, contain(ParamInfo) is false: hasDefaultValue is true, it will return defaultValue. hasDefaultValue is false, it will throw exception. developer should use contain to check that Params has ParamInfo or not.
* add size, clear, isEmpty, contains, fromJson in Params
* fix ParamInfo, PipelineStage to adapt new Params
* add test cases about aliases
