Exporting/Querying Yarn LEVELDB Content

sdutta — Sat, 25 Jun 2016 03:05:12 GMT

We are interested in querying and exporting the Yarn AppTimelIine Server content for external reporting.

Is there any documentation or method to query and export the data.

What is the best way to do this?

I found this on apache's website

http://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/TimelineServer.html#Accessing_generic-data_via_command-line

Querying the Timeline Server is currently only supported via REST API calls. Please see this link for some good information about working with the Timeline Server REST API:

https://hadoop.apache.org/docs/r2.7.1/hadoop-yarn/hadoop-yarn-site/TimelineServer.html#Timeline_Server_REST_API_v1
