Yerui Sun created KYLIN-1894: -------------------------------- Summary: GlobalDictionary may corrupt when server suddenly crash Key: KYLIN-1894 URL: https://issues.apache.org/jira/browse/KYLIN-1894 Project: Kylin Issue Type: Improvement Components: Metadata Affects Versions: v1.5.3 Reporter: Yerui Sun Assignee: Yerui Sun Fix For: v1.5.3
Global Dictionary store data on hdfs directly, and overwrite directly when data file updated. If the server crashed suddenly during writing file, the data file may be corrupt and can't be recovered. To resolve this problem, copy the data file into a tmp directory and copy back after the file is updated successfully. I'll post a patch later with this solution. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
