Two questions about node label support in CDH 5.4.x.
1. The docs for CDH 5.4.x make no mention of node labels that I can find.
Since 5.4.x includes Apache Hadoop 2.6 which supports node labels I would expect they are supported, but can find no official statement.
Are node labels supported in CDH 5.4.x?
2. Are node labels supported in the Fair Scheduler or just the Capacity Scheduler?
Based on this JIRA it would seem I can't make use of node labels if I use the Fair Scheduler.
Is there any way around this?
I am looking for node label support in CDH 5.7.1. Please let me know if there is any progress and documentation for it's implementation.
