Known Issues Fixed in CDH 5.0.3
The following topics describe known issues fixed in CDH 5.0.3. See What's New in CDH 5.0.3 for a list of the most important upstream problems fixed in this release.
Apache Hadoop
MapReduce
YARN Fair Scheduler's Cluster Utilization Threshold check is broken
Bug: YARN-2155
Severity: Medium
Workaround: Set the yarn.scheduler.fair.preemption.cluster-utilization-threshold property in yarn-site.xml to -1.
Apache Oozie
— When Oozie is configured to use MRv1 and SSL, YARN / MRv2 libraries are erroneously included in the classpath instead
This problem causes much of the configured Oozie functionality to be unusable.
Bug: None
Severity: Medium
Workaround: Use a different configuration (non-SSL or YARN), if possible.
