Error Observed:No Port in URLRoot Cause:

  • The configuration property oozie.https.enabled was newly introduced in 3.3.6.2-1.

  2. Add the following property:
oozie.https.enabled = false
  1. Restart the Oozie service.

Druid Shuts Down After Ambari Upgrade to 3.0.0

# Set DRUID specific environment variables here.
# Define paths for the log files and heap dumps
# The java implementation to use.
export JAVA_HOME={{java8_home}}
export PATH=$JAVA_HOME/bin:$PATH
export DRUID_PID_DIR={{druid_pid_dir}}
export DRUID_LOG_DIR={{druid_log_dir}}
export DRUID_CONF_DIR={{druid_conf_dir}}
export DRUID_LIB_DIR={{druid_home}}/lib
export HADOOP_CONF_DIR={{hadoop_conf_dir}}
##export ssl password variables:
export DRUID_CLIENT_HTTPS_TRUSTSTOREPASSWORD=`{{password_command}} -a "druid.client.https.trustStorePassword" `
export DRUID_SERVER_HTTPS_KEYSTOREPASSWORD=`{{password_command}} -a "druid.server.https.keyStorePassword"`
##export metadata password variable:
