[ https://issues.apache.org/jira/browse/HDFS-5845?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Suresh Srinivas updated HDFS-5845:
----------------------------------
Priority: Blocker (was: Major)
> SecondaryNameNode dies when checkpointing with cache pools
> ----------------------------------------------------------
>
> 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
>
> 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}
