I have installed "com.databricks:spark-xml_2.12:0.16.0" maven libraries to a cluster. The installation was successful. But when I restart the cluster, even this successful installation becomes failed. This happens with all Maven Libraries. 

Here is the error message:

Library installation attempted on the driver node of cluster 0502-152920-976jb2gj and failed. Please refer to the following error message to fix the library or contact Databricks support. Error Code: DRIVER_LIBRARY_INSTALLATION_FAILURE. Error Message: Library resolution failed because org.jvnet.jaxb2.maven2:maven-jaxb2-plugin-project download failed.
