[jira] [Created] (SPARK-23974) Do not allocate more containers as
expected in dynamic allocation
Darcy Shen created SPARK-23974:
----------------------------------
Summary: Do not allocate more containers as expected in dynamic allocation
Key: SPARK-23974
URL: https://issues.apache.org/jira/browse/SPARK-23974
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 2.1.1
Reporter: Darcy Shen
Using Yarn with dynamic allocation enabled, spark does not allocate more containers when current containers(executors) number is less than the max executor num.
For example, we only have 7 executors working, while our cluster is not busy, and I have set
{{ spark.dynamicAllocation.maxExecutors = 600}}
{{and the current jobs of the context are executed slowly.}}
