-----------------------------
Summary: Simplify the logs for queue initialization
Key: YARN-5998
URL: https://issues.apache.org/jira/browse/YARN-5998
Project: Hadoop YARN
Issue Type: Bug
Reporter: Jian He
When the reInitializeQueue command is fired or when RM starts up, a bunch of
logs related to queue structures are printed, which is not easy to read.
We can make it simpler with a structured format, like:
{code}
root (capacity = 1.0, max-capacity=1.0 etc.)
| -- queue1 (capacity = 0.0, max-capacity = 0.5 etc)
| -- queue2
| -- .....
{code}
This makes much easier for human read and debug.
