-----------------------------------
Summary: Bring back the hive-site.xml support for Spark 2.0
Key: SPARK-15887
URL: https://issues.apache.org/jira/browse/SPARK-15887
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.0.0
Reporter: Wenchen Fan
Assignee: Wenchen Fan
Right now, Spark 2.0 does not load hive-site.xml. Based on users' feedback, it
seems make sense to still load this conf file.
Originally, this file was loaded when we load HiveConf class and all settings
can be retrieved after we create a HiveConf instances. Let's avoid of using
this way to load hive-site.xml. Instead, since hive-site.xml is a normal hadoop
conf file, we can first find its url using the classloader and then use Hadoop
Configuration's addResource (or add hive-site.xml as a default resource through
Configuration.addDefaultResource) to load confs.
Please note that hive-site.xml needs to be loaded into the hadoop conf used to
create metadataHive.
