nickwallen opened a new pull request #1345: METRON-2012 Unable to Execute Stellar Functions Against HBase in the REPL URL: https://github.com/apache/metron/pull/1345 When running any functions that attempt to access HBase from the REPL, an IllegalAccessError exception is thrown. This can be replicated with Stellar functions like ENRICHMENT_GET and PROFILE_GET that attempt to read from HBase. To replicate, start the Stellar REPL with HBase and Zookeeper running and accessible. ``` [root@node1 ~]# source /etc/default/metron [root@node1 ~]# cd $METRON_HOME [root@node1 0.7.1]# bin/stellar -z

### Changes The Stellar REPL is being launched in a manner that pulls in multiple conflicting versions of Guava. Guava 17 was being used by `metron-management` and `metron-parsers-storm`, but the `metron-profiler-client` was unexpectedly pulling in Guava 12 through the `metron-hbase` project. * Altered the Profiler Client so that it does not depend on Guava. * Excluded Guava from any Profiler Client dependencies. * Removed unnecessary Hadoop dependencies from the Profiler family of projects. * Ensure that Netty 4.1.13 is explicitly being pulled in for the Elasticsearch integration tests. ### What's Lacking? * We do not have any automated tests that would have caught this issue. To do that we would need some tests that exercise the REPL after it is launched using the $METRON_HOME/bin/stellar script along with the deployed shaded JARs. ### Testing #### End to End 1. Ensure that we can continue to parse, enrich, and index telemetry. Launch the development environment and ensure that telemetry is visible within the Alerts UI. #### Streaming Enrichment 1. Create a Streaming Enrichment [by following these instructions](https://cwiki.apache.org/confluence/display/METRON/2016/06/16/Metron+Tutorial+-+Fundamentals+Part+6%3A+Streaming+Enrichment). 1. Define the streaming enrichment and save it as a new source of telemetry. ``` [Stellar]>>> conf := SHELL_EDIT() { "parserClassName": "org.apache.metron.parsers.csv.CSVParser", "writerClassName": "org.apache.metron.enrichment.writer.SimpleHbaseEnrichmentWriter", "sensorTopic": "user", "parserConfig": { "shew.table": "enrichment", "shew.cf": "t", "shew.keyColumns": "ip", "shew.enrichmentType": "user", "columns": { "user": 0, "ip": 1 } } } [Stellar]>>> [Stellar]>>> CONFIG_PUT("PARSER", conf, "user") ``` 1. Go to the Management UI and start the new parser called 'user'. 1. Create some test telemetry. ``` [Stellar]>>> msgs := ["user1,192.168.1.1", "user2,192.168.1.2", "user3,192.168.1.3"] [user1,192.168.1.1, user2,192.168.1.2, user3,192.168.1.3] [Stellar]>>> KAFKA_PUT("user", msgs) 3 [Stellar]>>> KAFKA_PUT("user", msgs) 3 [Stellar]>>> KAFKA_PUT("user", msgs) 3 ``` 1. Ensure that the enrichments are persisted in HBase. ``` [Stellar]>>> ENRICHMENT_GET('user', '192.168.1.1', 'enrichment', 't') {original_string=user1,192.168.1.1, guid=a6caf3c1-2506-4eb7-b33e-7c05b77cd72c, user=user1, timestamp=1551813589399, source.type=user} [Stellar]>>> ENRICHMENT_GET('user', '192.168.1.2', 'enrichment', 't') {original_string=user2,192.168.1.2, guid=49e4b8fa-c797-44f0-b041-cfb47983d54a, user=user2, timestamp=1551813589399, source.type=user} [Stellar]>>> ENRICHMENT_GET('user', '192.168.1.3', 'enrichment', 't') {original_string=user3,192.168.1.3, guid=324149fd-6c4c-42a3-b579-e218c032ea7f, user=user3, timestamp=1551813589402, source.type=user} ``` #### Profiler 1. Test a profile in the REPL according to [these instructions](https://github.com/apache/metron/tree/master/metron-analytics/metron-profiler-repl#getting-started). ``` [Stellar]>>> values := PROFILER_FLUSH(profiler) [{period={duration=900000, period=1723089, start=1550780100000, end=1550781000000}, profile=hello-world, groups=[], value=4, entity=192.168.138.158}] ``` 1. Deploy that profile to the Streaming Profiler. ``` [Stellar]>>> CONFIG_PUT("PROFILER", conf) ``` 1. Wait for the Streaming Profiler in Storm to flush and retrieve the measurement from HBase. For the impatient, you can reset the period duration to 1 minute. Alternatively, you can allow the Profiler topology to work for a minute or two and then kill the `profiler` topology which will force it to flush a profile measurement to HBase. Retrieve the measurement from HBase. Prior to this PR, it was not possible to query HBase from the REPL. ``` [Stellar]>>> PROFILE_GET("hello-world","192.168.138.158",PROFILE_FIXED(30,"DAYS")) [2979] ``` 1. Install Spark using Ambari. 1. Stop Storm, YARN, Elasticsearch, Kibana, and Kafka. 1. Install Spark2 using Ambari. 1. Ensure that Spark can talk with HBase. ``` cp /etc/hbase/conf/hbase-site.xml /etc/spark2/conf/ ``` 1. Use the Batch Profiler to back-fill your profile. To do this, follow the direction [provided here](https://github.com/apache/metron/tree/master/metron-analytics/metron-profiler-spark#getting-started). 1. Retrieve the entire profile, including the back-filled data. ``` [Stellar]>>> PROFILE_GET("hello-world","192.168.138.158",PROFILE_FIXED(30,"DAYS")) [1203, 2849, 2900, 1944, 1054, 1241, 1721] ``` ## Pull Request Checklist - [x] Is there a JIRA ticket associated with this PR?
