ASF GitHub Bot commented on METRON-1587: ---------------------------------------- GitHub user merrimanr opened a pull request: https://github.com/apache/metron/pull/1043 METRON-1587: Make collection utility work for HDP search ## Contributor Comments This PR improves the metron-solr create_collection.sh and delete_collection.sh scripts by switching to the Solr REST api instead of the Solr CLI tools. This removes the requirement that Metron is colocated with a Solr client and makes the scripts easier to use with different versions and distributions. Now only a zookeeper client is required for retrieving a Solr node address. I refactored the Ambari code a little bit to match the rest of our MPack. The solr_schema_install and solr_schema_delete functions were moved from indexing_master.py to indexing_commands.py because specific, low-level functions are generally in the *_commands.py scripts. If this is confusing, doesn't make sense or makes reviewing this harder I'm happy to move them back. I also added Kerberos support to these scripts. The way I've done it creates a dependency on the HDP Search 3 Mpack but makes configuring Kerberos easy with no configuration required. I would like to hear what the community thinks about this approach. If we do decide to make this a dependency I can also remove the Solr zookeeper configuration setting in Ambari. At that point using Solr is as easy as switching the "Random Access Search Engine" setting. This has been tested in full dev with Kerberos enabled. To test this PR, first install HDP Search 3 in full dev (https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.4/bk_solr-search-installation/content/hdp-search30-install-mpack.html). Kerberos can also be enabled now if desired. Then in Ambari set "Solr Zookeeper Urls" in the "Index Settings" tab to `node1:2181/solr` and change the "Random Access Search Engine" setting in the Indexing tab to `Solr`. Now stop the Metron Indexing component, then start it. Note that restart does not trigger automatic Solr collection creation, matching how ES template loading works. If we think adding collection creation on restart is desirable I can make that change. Collections (bro, snort, metaalert, yaf, error) should now be present in Solr at node1:8983. The scripts can also be tested independently from Ambari. Just have to set a few environment variables first: ``` export ZOOKEEPER=node1:2181/solr export SECURITY_ENABLED=true # if Kerberos is enabled ``` Then the scripts should work when executed directly. For example, to create the bro collection: ``` $METRON_HOME/bin/create_collection.sh bro ``` and to delete the bro collection: ``` $METRON_HOME/bin/delete_collection.sh bro ``` ## Pull Request Checklist Thank you for submitting a contribution to Apache Metron.
