wget http://search.maven.org/remotecontent?filepath=com/sleepycat/je/5.0.73/je-5.0.73.jar -O /usr/share/je-5.0.73.jar
chmod 644 /usr/share/je-5.0.73.jar
ambari-server setup --jdbc-db=bdb --jdbc-driver=/usr/share/je-5.0.73.jar  
## /etc/ambari-server/conf/ambari.properties 文件下
## custom.bdb.jdbc.name=je-5.0.73.jar && previous.custom.bdb.jdbc.name=je-5.0.73.jar
ambari-server restart
界面上重启Falcon

这样，貌似是会把je-5.0.73.jar分发到/usr/hdp/2.6.4.0-91/falcon/webapp/falcon/WEB-INF/lib目录下。
