​Configure and Validate Apache Falcon

[Note]Note

In HDP-2.5, if authorization is enabled (for example, in the startup.properties file with *.falcon.security.authorization.enabled=true") then Access Control List (ACL) is mandated for all entities.

Upgrade Falcon after you have upgraded HDFS, Hive, Oozie, and Pig. Stop Oozie jobs while running Falcon.

[Important]Important

We recommend upgrading Falcon from HDP 2.1 to HDP 2.2 and then upgrading from HDP 2.2 to HDP 2.5.

Upgrade Apache Falcon from HDP 2.1 to HDP 2.2

  1. Upgrade Falcon from HDP 2.1 to HDP 2.2.

    • RHEL/CentOS/Oracle 6

      1. Download the HDP 2.2.9 hdp.repo file:

        wget -nv https://hdpweb.o.onslip.net/HDP/centos<version>/2.x/updates/2.2.9.0/hdp.repo -0 /etc/yum.repos.d/hdp.repo

      2. Install the HDP 2.2.9 version of Falcon:

        yum install "falcon"

    • SLES

      1. Download the HDP 2.2.9 hdp.repo file:

        wget -nv https://hdpweb.o.onslip.net/HDP/sles11sp1/2.x/updates/2.2.9.0/hdp.repo -O /etc/zypp/repos.d/hdp.repo

      2. Install the HDP 2.2.9 version of Falcon:

        zypper install "falcon"

    • SLES

      1. Download the HDP 2.2.0 hdp.repo file:

        https://hdpweb.o.onslip.net/HDP/suse11sp3/2.x/updates/2.2.9.0/hdp.repo -O /etc/zypp/repos.d/hdp.repo

      2. Install the HDP 2.2.9 version of Falcon:

        zypper install "falcon"

    • Ubuntu 12

      1. Download the HDP 2.2 hdp.repo file:

        wget https://hdpweb.o.onslip.net/HDP/ubuntu12/2.x/updates/2.2.9.0/hdp.list -O /etc/apt/sources.list.d/hdp.list

      2. Install the HDP 2.2.9 version of Falcon:

        apt-get install "falcon"

    • Debian

      1. Download the HDP 2.2 hdp.repo file:

        wget -nv https://hdpweb.o.onslip.net/HDP/debian<version>/2.x/updates/2.2.9.0/hdp.list -O /etc/apt/sources.list.d/hdp.list

      2. Install the HDP 2.2.9 version of Falcon:

        apt-get install "falcon"

  2. Verify start.properties. In Falcon 2.2, TLS is enabled by default. When TLS is enabled, Falcon starts on https:/<falcon_host>:15443/. You can disable TLS by adding the following line in startup.properties:

    *.falcon.enableTLS=false

  3. Verify the client.properties file. If TLS is disabled, make sure the property falcon.url is set as follows:

    falcon.url=http://localhost:15000/

  4. Install the hotfix provided by Hortonworks customer support to migrate entities in bulk.

  5. Restart Falcon.

    su - falcon -c "cd /usr/hdp/2.2.9.0-$BUILD/falcon/bin/falcon-start"

  6. Run Falcon CLI to update Falcon entities from HDP 2.1 to HDP 2.2. This script also updates the ownership and permissions of staging and working directories of cluster entitles. Run this script as user falcon.

    falcon upgrade -owner hrt_qa -group users -configDir <falcon_config_store> -backupDir/tmp/

    Where:

    • Owner and group are used to set ACL for Falcon entities.

    • configDir refers to the location where Falcon stores its entities. This directory should be the ssame location as the value of property *.config.store.uri in the file conf/startup.properties.

    • backupDir is the location where Falcon 2.1 entitles are copied as backup. User can restore entitis from this directory.

  7. Restart Falcon.

    su - falcon -c "cd /usr/hdp/2.2.9.0-$BUILD/falcon/bin/falcon-start"

  8. Replace your configuration after upgrading. Copy /etc/falcon/conf from the template to the conf directory in falcon hosts.

  9. Check your Falcon entities. There should be no changes, but in some cases you may need to update your entities post-upgrade.
