Allow ignoring SSL cert when connecting to gerrit Introduce a new boolean flag '--ignore-ssl-cert' (false by default), to ignore validating SSL certificate. This is useful when connecting to gerrit servers installed with self-signed certificate. Feature: Issue 10097 Change-Id: I3467800c46123d42e8f7e37fb51a0eebf6e357d1
This repository provides a set of spark ETL jobs able to extract, transform and persist data from gerrit projects with the purpose of performing analytics tasks.
Each job focuses on a specific dataset and it knows how to extract it, filter it, aggregate it, transform it and then persist it.
The persistent storage of choice is elasticsearch, which plays very well with the kibana dashboard for visualizing the analytics.
All jobs are configured as separate sbt projects and have in common just a thin layer of core dependencies, such as spark, elasticsearch client, test utils, etc.
Each job can be built and published independently, both as a fat jar artifact or a docker image.
Here below an exhaustive list of all the spark jobs provided by this repo, along with their documentation.
Extracts and aggregate git commits data from Gerrit Projects.
Requires a Gerrit 2.13.x or later with the analytics plugin installed and Apache Spark 2.11 or later.
Job can be launched with the following parameters:
bin/spark-submit \ --class com.gerritforge.analytics.gitcommits.job.Main \ --conf spark.es.nodes=es.mycompany.com \ $JARS/analytics-etl-gitcommits.jar \ --since 2000-06-01 \ --aggregate email_hour \ --url http://gerrit.mycompany.com \ --events file:///tmp/gerrit-events-export.json \ --writeNotProcessedEventsTo file:///tmp/failed-events \ -e gerrit \ --username gerrit-api-username \ --password gerrit-api-password
You can also run this job in docker:
docker run -ti --rm \ -e ES_HOST="es.mycompany.com" \ -e GERRIT_URL="http://gerrit.mycompany.com" \ -e ANALYTICS_ARGS="--since 2000-06-01 --aggregate email_hour --writeNotProcessedEventsTo file:///tmp/failed-events -e gerrit" \ gerritforge/gerrit-analytics-etl-gitcommits:latest
since, until, aggregate are the same defined in Gerrit Analytics plugin see: https://gerrit.googlesource.com/plugins/analytics/+/master/README.md
-u --url Gerrit server URL with the analytics plugins installed
-p --prefix (optional) Projects prefix. Limit the results to those projects that start with the specified prefix.
-e --elasticIndex Elastic Search index name. If not provided no ES export will be performed
-o --out folder location for storing the output as JSON files if not provided data is saved to /analytics- where is the system temporary directory
-a --email-aliases (optional) “emails to author alias” input data path.
--events location where to load the Gerrit Events If not specified events will be ignored
--writeNotProcessedEventsTo location where to write a TSV file containing the events we couldn't process with a description fo the reason why
-k --ignore-ssl-cert allows to proceed even for server connections otherwise considered insecure.
CSVs with 3 columns are expected in input.
Here an example of the required files structure:
author,email,organization John Smith,john@email.com,John's Company John Smith,john@anotheremail.com,John's Company David Smith,david.smith@email.com,Indipendent David Smith,david@myemail.com,Indipendent
You can use the following command to quickly extract the list of authors and emails to create part of an input CSV file:
echo -e "author,email\n$(git log --pretty="%an,%ae%n%cn,%ce"|sort |uniq )" > /tmp/my_aliases.csv
Once you have it, you just have to add the organization column.
NOTE:
To build the jar file, simply use
sbt analyticsETLGitCommits/assembly
To build the gerritforge/gerrit-analytics-etl-gitcommits docker container just run:
sbt analyticsETLGitCommits/docker.
If you want to distribute use:
sbt analyticsETLGitCommits/dockerBuildAndPush.
The build and distribution override the latest image tag too Remember to create an annotated tag for a release. The tag is used to define the docker image tag too
If you want to run the git commits ETL job from within docker you need to make elasticsearch and gerrit available to it. You can do this by:
analytics-etl_ek if you used the docker-compose provided by this repo)--add-host="gerrit:<your_host_ip_address>")For example:
HOST_IP=`ifconfig en0 | grep "inet " | awk '{print $2}'` \ docker run -ti --rm \ --add-host="gerrit:$HOST_IP" \ --network analytics-etl_ek \ -e ES_HOST="elasticsearch" \ -e GERRIT_URL="http://$HOST_IP:8080" \ -e ANALYTICS_ARGS="--since 2000-06-01 --aggregate email_hour --writeNotProcessedEventsTo file:///tmp/failed-events -e gerrit" \ gerritforge/gerrit-analytics-etl-gitcommits:latest
A docker compose file is provided to spin up an instance of Elastisearch with Kibana locally. Just run docker-compose up.
If Elastisearch dies with exit code 137 you might have to give Docker more memory (check this article for more details)
Should ElasticSearch need authentication (i.e.: if X-Pack is enabled), credentials can be passed through the spark.es.net.http.auth.pass and spark.es.net.http.auth.user parameters.
If the dockerized spark job cannot connect to elasticsearch (also, running on docker) you might need to tell elasticsearch to publish the host to the cluster using the _site_ address.
elasticsearch:
...
environment:
...
- http.host=0.0.0.0
- network.host=_site_
- http.publish_host=_site_
...
See here for more info
To perform actions across all jobs simply run the relevant sbt task without specifying the job name. For example:
sbt testsbt assemblysbt docker
