Hello,   I'm currently installing CDH 5.8.1 on a Centos Environement with one name node and 2 data nodes.   The install was made using packages because the P2P ports where blocked. The install of HDFS, Zookeeper, Map Reduce, Hue, Hive went very well but I have a problem to install Sqoop2 using the Cloudera manager, we have the error below during the start of the server - log from stderr. The user cloudera-scm has the same access as root to all files.   How can we resolve the problem ?    Thank you + mkdir -p /var/run/cloudera-scm-agent/process/290-sqoop-SQOOP_SERVER/temp + EXT_LIBS_DIR=/var/lib/sqoop2 + cp /usr/share/java/mysql-connector-java.jar /var/lib/sqoop2 + cp /usr/share/cmf/lib/postgresql-9.0-801.jdbc4.jar /var/lib/sqoop2 + cp /usr/share/java/oracle-connector-java.jar /var/lib/sqoop2 + '[' '' == upgrade -o '' == create-database ']' + exec /usr/lib/bigtop-tomcat/bin/catalina.sh run aot 11, 2016 10:43:02 AM org.apache.catalina.startup.Catalina load AVERTISSEMENT: Can't load server.xml from /var/lib/sqoop2/tomcat-deployment/conf/server.xml aot 11, 2016 10:43:02 AM org.apache.catalina.startup.Catalina load AVERTISSEMENT: Can't load server.xml from /var/lib/sqoop2/tomcat-deployment/conf/server.xml aot 11, 2016 10:43:02 AM org.apache.catalina.startup.Catalina start GRAVE: Cannot start server.
