IllegalArgumentException with Hive when executing query - hadoop

Question

Ok so I'm trying to execute SHOW DATABASES on hive, but then when I do it, it returns this error
Failed with exception java.io.IOException:java.lang.IllegalArgumentException: java.net.URISyntaxException: Relative path in absolute URI: ${system:user.name%7D
I've checked around in my XML to see what's going one, but nothing I change fixes this error.
Here's the relevant parts of the XML:
<property>
<name>hive.exec.scratchdir</name>
<value>/tmp/hive-${user.name}</value>
<description>HDFS root scratch dir for Hive jobs which gets created with write all (733) permission. For each connecting user, an HDFS scratch dir: ${hive.exec.scratchdir}/<username> is created, with ${hive.scratch.dir.permission}.</description>
</property>
<property>
<name>hive.exec.local.scratchdir</name>
<value>/tmp/${system:user.name}</value>
<description>Local scratch space for Hive jobs</description>
</property>
<property>
<name>hive.downloaded.resources.dir</name>
<value>/tmp/${hive.session.id}_resources</value>
<description>Temporary local directory for added resources in the remote file system.</description>
</property>
<property>
<name>hive.scratch.dir.permission</name>
<value>733</value>
<description>The permission for the user specific scratch directories that get created.</description>
</property>
<property>
<name>hive.querylog.location</name>
<value>/tmp/${system:user.name}</value>
<description>Location of Hive run time structured log file</description>
</property>
Other than that, I can't think of any other property causing those errors, but then again I'm completely new this. I still haven't figured out a lot of things, for example how to connect my windows program in my windows VM to hive in my linux VM.
Anyway, if I can get any help I'd appreciate it.

Answer 1

What is ${system:user.name}? Why not use ${user.name} for hive.exec.local.scratchdir and hive.querylog.location. It seems like ${system:user.name} is not expanded.
