---------------------------------------
Summary: [Atsv2] Publish parent/child entities value as string
rather than value as object.
Key: YARN-5577
URL: https://issues.apache.org/jira/browse/YARN-5577
Project: Hadoop YARN
Issue Type: Bug
Components: timelinereader, timelineserver
Reporter: Rohith Sharma K S
Assignee: Rohith Sharma K S
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.
{code}
"SYSTEM_INFO_PARENT_ENTITY": {
"type": "YARN_APPLICATION",
"id": "application_1471931266232_0024"
}
{code}
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
{code}
"SYSTEM_INFO_PARENT_ENTITY_TYPE": "YARN_APPLICATION"
"SYSTEM_INFO_PARENT_ENTITY_ID":"application_1471931266232_0024"
{code}
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.
