Change default timezone for Hive

[#1]

Which timezone setting (OS/Hadoop Core/HDFS/Hive etc.) is used as the default timezone for Hive?

Which configuration / property to change to use a different timezone?

[#2]

Hive uses the default timezone of the JVM. Currently the only way to change the timezone used by Hive is to change the default timezone of the JVM.

[#3]

According to this post HDP uses UTC as default but a simple Hive Statement like this and multiple JIRA Issues proves that isn't true.

select concat('Example: ',cast(cast('2017-03-12 02:00:00' as timestamp) as string));

Example: 2017-03-12 03:00:00

Can someone provide guidance on how to set the JVMs Timezone?
