Hive 2.3.2 Local Mode Cannot Find Hadoop Installation

According to what I've been reading, you can run Hive without Hadoop or HDFS (like in cases of using Spark or Tez), i.e. in local mode by setting the fs.default.name and hive.metastore.warehouse.dir to local paths. However, when I do this, I get an error:

Starting Hive metastore service.
Cannot find hadoop installation: $HADOOP_HOME or $HADOOP_PREFIX must be set or hadoop must be in the path

My hive-site.xml file:

<property>
  <name>mapred.job.tracker</name>
  <value>local</value>
</property>
<property>
  <name>hive.metastore.schema.verification/name>
  <value>false</value>
</property>
<property>
  <name>hive.metastore.warehouse.dir</name>
  <value>file:///tmp/hive/warehouse</value>
</property>
<property>
  <name>fs.default.name</name>
  <value>file:///tmp/hive</value>
</property>

Does this mean that I still need to have all of the hadoop binaries downloaded and have HADOOP_HOME set to that path? Or does local mode in hive allow me to run without needing all of that content?

Hive doesn't require HDFS or YARN to execute, but it still requires the Hadoop input / output formats like Spark
