Andrew Wang created HDFS-5845: --------------------------------- Summary: 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
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} -- This message was sent by Atlassian JIRA (v6.1.5#6160)
