Summary: Consolidate data model change according the backend
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Zhijie Shen
Assignee: Zhijie Shen
Based on the comments on
we need to change the data model to restrict the data type of
1. Info: the value could be all kinds object that is able to be
serialized/deserialized by jackson.
2. Config: the value will always be assumed as String.
3. Metric: single data or time series value have to be number for aggregation.
Other than that, info/start time/finish time of metric seem not to be necessary
for storage. They should be removed.
