--------------------------------
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.
