[HIVE-17788] MetastoreConf not properly handling variable interpolation in config values

• Type: Bug
• Status: Open
• Priority: Major

Description

HiveConf allows the user to put System properties into values in the conf file, which will later be interpolated at read time. For example:

<property>
  <name>hadoop.tmp.dir</name>
  <value>${test.tmp.dir}/hadoop-tmp</value>
  <description>A base for other temporary directories.</description>
</property>

The value for test.tmp.dir is read from the System properties at runtime.

MetastoreConf is instead returning the uninterpolated value.
