------------------------------------------
Summary: Do not expose CachePool type in AddCachePoolOp
Key: HDFS-5314
URL: https://issues.apache.org/jira/browse/HDFS-5314
Project: Hadoop HDFS
Issue Type: Sub-task
Components: namenode
Affects Versions: HDFS-4949
Reporter: Colin Patrick McCabe
Assignee: Colin Patrick McCabe
{{CachePool}} is an internal type which should not be exposed or used in the
{{FSEditLog}}. Because {{CachePool}} is mutable, storing a reference to it in
an edit log operation could lead to the edit log operation changing as a result
of the {{CachePool}} object being changed. Instead, we should store
{{CachePoolInfo}}.
