Description of problem: The hadoop-httpfs RPM installs the Tomcat/Catalina configuration files for the Tomcat instance dedicated to httpFS. The reference installation directory is /usr/share/hadoop/httpfs/tomcat However, the Tomcat service cannot start: # systemctl start tomcat@httpfs # systemctl status tomcat@httpfs tomcat - Apache Tomcat Web Application Container Loaded: loaded (/usr/lib/systemd/system/tomcat@.service; disabled; vendor preset: disabled) Active: inactive (dead) The error is explicit in the /var/log/hadoop-httpfs/httpfs-catalina.YYYY-MM-DD.log: 05-Jan-2016 23:30:26.891 WARNING [main] org.apache.catalina.startup.Catalina.load Catalina.start using conf/server.xml: Error at (32, 67) : org.apache.catalina.core.JasperListener 05-Jan-2016 23:30:26.897 SEVERE [main] org.apache.tomcat.util.digester.Digester.startElement Begin event threw exception java.lang.ClassNotFoundException: org.apache.catalina.core.JasperListener at java.net.URLClassLoader.findClass(URLClassLoader.java:381) It is due to the fact that the server.xml configuration file contains lines to load the JasperListener. Whereas the Tomcat version delivered with Fedora 23 does not include those two lines. As a matter of fact, as a manual work around: * I copied/pasted all the configuration files of Tomcat (from /etc/tomcat/) into /etc/hadoop/tomcat/ * In server.xml, changed the default ports (8005 for admin, 8080 for the service, into respectively ${httpfs.admin.port} and ${httpfs.http.port}). * In logging.properties, changed ${catalina.base} into ${httpfs.log.dir} Those three tasks fixed the issue. So, the real key is to pull out the configuration files corresponding to the Tomcat version of the current Fedora release. Version-Release number of selected component (if applicable): $ rpm -q hadoop-httpfs hadoop-httpfs-2.4.1-11.fc23.noarch How reproducible: Always Steps to Reproduce: 1. Install hadoop-httpfs 2. Try to start the tomcat@httpfs service 3. Query the status of the tomcat@httpfs service, and check the logs in /var/log/hadoop-httpfs/ Actual results: The tomcat@httpfs service cannot start. Expected results: The tomcat@httpfs service should start.
