merrimanr opened a new pull request #1519: METRON-2265: Update Kerberos settings URL: https://github.com/apache/metron/pull/1519 ## Contributor Comments This PR includes code and documentation changes for enabling Kerberos in HDP 3.1. The primary changes needed were minor Maven changes and making the Metron JAAS setting available to Kafka through `KAFKA_OPTS`. ### Changes Included - Changes to KDC setup documentation for Centos7 - Changes to Kerberos setup documentation for HDP 3.1 - Minor Mpack change for looking up a host name - Addition of a `CLIENT_JAAS_ARG` property to `/etc/default/metron`. This is needed separately from `METRON_JVMFLAGS ` - Updated the Kafka `security.protocol` setting to `SASL_PLAINTEXT` - Maven changes to handle classpath errors that result from the extra jars added by Storm when Kerberos is enabled. The extra jars are located in `/usr/hdp/current/storm-supervisor/external/storm-autocreds/*`. - Replaced a call to `org.apache.commons.math.util.MathUtils` with a standard Java implementation. This dependency was being pulled in transitively. - Fixed a bug in `metron-data-management` that resulted from `com.google.thirdparty` not being shaded. ### Testing I attempted to test the various components (Storm, Kafka, HBase, Hadoop, etc) to verify they still work after Kerberos is enabled. The instructions in `Kerberos-manual-setup.md` should now be correct. Also there should not be any additional steps needed to enabled the sensor stubs other than a simple restart. I tested the following after spinning up full dev: - Verified data is flowing through to ES and HDFS and the Alerts UI works. - Verified the various Profiler README examples work - Verified the `flatfile_loader.sh` script works as expected - Verified Stellar works with Kafka (added docs for this) I believe this should cover almost all of the components. There were not any specific Solr changes required (was done in the [Solr upgrade PR](https://issues.apache.org/jira/browse/METRON-2225)) but we might want to test this too. ## Pull Request Checklist Thank you for submitting a contribution to Apache Metron.
