---------------------------------
Summary: Implement regex querying of logs
Key: YARN-10032
URL: https://issues.apache.org/jira/browse/YARN-10032
Project: Hadoop YARN
Issue Type: Sub-task
Components: yarn
Affects Versions: 3.2.1
Reporter: Adam Antal
Assignee: Adam Antal
Fix For: 3.3.0
After YARN-10031, we have query parameters to the log servlet's GET endpoint.
To demonstrate the new capabilities of the log servlet and how easy it will be
to add a functionality to all log servlets at the same time: let's add the
ability to search in the aggregated logs with a given regex.
A conceptual use case:
User run several MR jobs daily, but some of them fail to localize a particular
resource at first. We want to search in the logs of these Yarn applications,
and extract some data from them.
