> Key: HDFS-5845
> URL: https://issues.apache.org/jira/browse/HDFS-5845
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: namenode
> Affects Versions: 2.3.0
> Reporter: Andrew Wang
> Assignee: Andrew Wang
> Priority: Blocker
> Labels: caching
> Fix For: 2.3.0

>
> The SecondaryNameNode clears and reloads its FSNamesystem when doing
> checkpointing. However, FSNamesystem#clear does not clear CacheManager state
> during this reload. This leads to an error like the following:
> {noformat}
> org.apache.hadoop.fs.InvalidRequestException: Cache pool pool1 already exists.
> {noformat}
