Jiandan Yang created HDFS-12348: ------------------------------------ Summary: disable removing block to trash while rolling upgrade Key: HDFS-12348 URL: https://issues.apache.org/jira/browse/HDFS-12348 Project: Hadoop HDFS Issue Type: New Feature Components: datanode Reporter: Jiandan Yang Assignee: Jiandan Yang
DataNode remove block file and meta file to trash while rolling upgrade,and do delete when executing finalize. But frequently creating and deleting files leads to disk to be full(eg,Hbase compaction), and we will not rollbacking namespace in production when rolling upgrade fail. Disable trash of datanode maybe a good method to avoid disk to be full. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
