In HierarchicalTimelineEntity, setparent/addChild allows to set parent/child entities at INFO level. The key is an string and value as an object.
Like below, for YARN_CONTAINER entity parent entity set for application.
"SYSTEM_INFO_PARENT_ENTITY": { "type": "YARN_APPLICATION", "id": "application_1471931266232_0024" }
But to use infofilter on entity type YARN_CONTAINER for an specific applicationId, IIUC there is no way to pass object as value in infofilter.
To make easier retrieval either
- publish parent/child entity id and type as string rather that object like below
"SYSTEM_INFO_PARENT_ENTITY_TYPE": "YARN_APPLICATION" "SYSTEM_INFO_PARENT_ENTITY_ID":"application_1471931266232_0024"
OR
- Add ability to provide object as filter with below format like infofilters=SYSTEM_INFO_PARENT_ENTITY eq ((type eq YARN_APPLICATION) AND (id eq application_1471931266232_0024))
I believe 2nd approach will be well applicable for any entities. But I am not sure does HBase supports such a custom filters while scanning a table.
1st approaches will be much easier to change.
