but I can't modify the ‘_’ character,
so I wan't to modify source code in source-kafka module
at StreamingParser.java class
```
static {
derivedTimeColumns.put("minute_start", 1);
derivedTimeColumns.put("hour_start", 2);
derivedTimeColumns.put("day_start", 3);
derivedTimeColumns.put("week_start", 4);
derivedTimeColumns.put("month_start", 5);
derivedTimeColumns.put("quarter_start", 6);
derivedTimeColumns.put("year_start", 7);
defaultProperties.put(PROPERTY_TS_COLUMN_NAME, "timestamp");
defaultProperties.put(PROPERTY_TS_PARSER,
"org.apache.kylin.source.kafka.DefaultTimeParser");
defaultProperties.put(PROPERTY_TS_PATTERN,
DateFormat.DEFAULT_DATETIME_PATTERN_WITHOUT_MILLISECONDS);
+ defaultProperties.put(EMBEDDED_PROPERTY_SEPARATOR, ".");
- defaultProperties.put(EMBEDDED_PROPERTY_SEPARATOR, "_");
}
````
and I rebuild this module and replace it to tomcat webapps
but error has still happened
I wonder Why?

Subject: Re: Support embedded JSON format ?
Hi,
It supports the embedded format, while has a conflict with "_" in the JSON.
You can check: https://issues.apache.org/jira/browse/KYLIN-3145
To bypass at this moment, you can create a message which has no "_" in the
property name.
