Release 0.10.1 (March 1, 2019)

Highlights

Upgrade Instructions from v0.10.0

  1. Please see Upgrade Instructions from v0.9.1 if upgrading from an earlier version of Kylo.
  2. Backup any Kylo plugins
When Kylo is uninstalled it will backup configuration files, but not the /plugin jar files. If you have any custom plugins in either kylo-services/plugin or kylo-ui/plugin then you will want to manually back them up to a different location.

  1. Stop and uninstall Kylo

    3.1 Stop Kylo

    /opt/kylo/stop-kylo-apps.sh

    3.2 Uninstall Kylo

    /opt/kylo/remove-kylo.sh

  2. Install the new RPM:

rpm –ivh <RPM_FILE>

  1. Restore previous application.properties files. If you have customized the the application.properties, copy the backup from the 0.10.0 install.

    5.1 Find the /bkup-config/TIMESTAMP/kylo-services/application.properties file

    • Kylo will backup the application.properties file to the following location, /opt/kylo/bkup-config/YYYY_MM_DD_HH_MM_millis/kylo-services/application.properties, replacing the “YYYY_MM_DD_HH_MM_millis” with a valid time:

    5.2 Copy the backup file over to the /opt/kylo/kylo-services/conf folder

    ### move the application.properties shipped with the .rpm to a backup file
mv /opt/kylo/kylo-services/conf/application.properties /opt/kylo/kylo-services/conf/application.properties.0_10_0_template
### copy the backup properties  (Replace the YYYY_MM_DD_HH_MM_millis  with the valid timestamp)
cp /opt/kylo/bkup-config/YYYY_MM_DD_HH_MM_millis/kylo-services/application.properties /opt/kylo/kylo-services/conf

    5.3 Copy the /bkup-config/TIMESTAMP/kylo-ui/application.properties file to /opt/kylo/kylo-ui/conf

    ### move the application.properties shipped with the .rpm to a backup file
mv /opt/kylo/kylo-ui/conf/application.properties /opt/kylo/kylo-ui/conf/application.properties.0_10_0_template
### copy the backup properties  (Replace the YYYY_MM_DD_HH_MM_millis  with the valid timestamp)
cp /opt/kylo/bkup-config/YYYY_MM_DD_HH_MM_millis/kylo-ui/application.properties /opt/kylo/kylo-ui/conf

    5.4 Ensure the property security.jwt.key in both kylo-services and kylo-ui application.properties file match. The property below needs to match in both of these files:

    • /opt/kylo/kylo-ui/conf/application.properties

    • /opt/kylo/kylo-services/conf/application.properties

      security.jwt.key=

  2. Update the NiFi nars.

    Stop NiFi

    service nifi stop

    Run the following shell script to copy over the new NiFi nars/jars to get new changes to NiFi processors and services.

    /opt/kylo/setup/nifi/update-nars-jars.sh <NIFI_HOME> <KYLO_SETUP_FOLDER> <NIFI_LINUX_USER> <NIFI_LINUX_GROUP>

Example:  /opt/kylo/setup/nifi/update-nars-jars.sh /opt/nifi /opt/kylo/setup nifi users

    Start NiFi

    service nifi start

  3. Start Kylo

/opt/kylo/start-kylo-apps.sh
