Project: Kylin
Issue Type: Bug
Components: Metadata
Affects Versions: v1.5.2
Reporter: Yerui Sun
Assignee: Yerui Sun
Priority: Critical
Fix For: v1.5.2
KylinConfigExt overrides getAllProperties() to merge the base properties and
the override properties into one Properties, which used to get config or write
into file.
In the following code, super properties stored in Properties.*defaults*, which
will *NOT* written out by store() method, quoted from [java
document|https://docs.oracle.com/javase/7/docs/api/java/util/Properties.html#store(java.io.OutputStream,%20java.lang.String)].
That will lost super properties when store KylinConfigExt into file.

protected Properties getAllProperties() {
Properties result = new Properties(super.getAllProperties());
result.putAll(overrides);
return result;
}
