Shaofeng SHI commented on KYLIN-1894: ------------------------------------- Hi Yerui, there is a doc on using the temp file in Kylin's development doc, could you please check and append another patch for it: https://kylin.apache.org/development/about_temp_files.html; Thanks! > 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 > > Attachments: KYLIN-1894.2.patch > > > 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)
