Description
After activating the spark external shuffle service for YARN in order to have dynamic ressource allocation I face those level db creation issues on the nodemanager:

... 14 more
On the yarn-site.xml config file I used URI to set path:
<property>
<description>List of directories to store localized files in.</description>
<name>yarn.nodemanager.local-dirs</name>
<value>file:///data/yarn/cache/${user.name}/nm-local-dir</value>
</property>
If I removed the scheme for this config in order to have /data/yarn/cache/${user.name}/nm-local-dir the nodemanager not face this issue and the level db is well created.
