----------------------------------
Summary: Decide which contents to retrieve and send back in
response in TimelineReader
Key: YARN-3862
URL: https://issues.apache.org/jira/browse/YARN-3862
Project: Hadoop YARN
Issue Type: Bug
Components: timelineserver
Affects Versions: YARN-2928
Reporter: Varun Saxena
Assignee: Varun Saxena
Currently, we will retrieve all the contents of the field if that field is
specified in the query API. In case of configs and metrics, this can become a
lot of data even though the user doesn't need it. So we need to provide a way
to query only a set of configs or metrics.
As a comma spearated list of configs/metrics to be returned will be quite
cumbersome to specify, we have to support either of the following options :
# Prefix match
# Regex
# Group the configs/metrics and query that group.
We also need a facility to specify a metric time window to return metrics in a
that window. This may be useful in plotting graphs
