----------------------------------
Summary: Kylin's internal time zone conversions are various and
confusing
Key: KYLIN-3788
URL: https://issues.apache.org/jira/browse/KYLIN-3788
Project: Kylin
Issue Type: Bug
Components: REST Service, Web
Affects Versions: v2.5.2
Environment: Huawei FI
Reporter: zhao jintao
I found that Kylin has a variety of time zone conversions inside, which is
confusing. In some code, the time zone is "GMT" when converting time, and some
code uses the time zone specified in the configuration file
("TimeZone.getTimeZone("GMT")" );
For Example:
in CubeSegment.java, use TimeZone from configuration file:
dataFormat.setTimeZone(TimeZone.getTimeZone("GMT")),
but in TimeUtil.java, use GMT TimeZone:private static TimeZone gmt =
TimeZone.getTimeZone("GMT")
When inport data from Kafka Streaming Data，kylin generate "Data_Start",
"Hour_Start" uses the GMT time zone, They are some time zones later than the
real time. Why not use the time zone specified in the configuration file?
