>> Proposal
>> Eagle audits access to HDFS files, Hive and HBase tables in real time,
>> enforces policies defined on sensitive data access and alerts or blocks

>> profiles based on the typical access behaviour for HDFS and Hive and sends

>> Overview of Eagle
>> Eagle has 3 main parts.
>> 1.Data collection and storage - Eagle collects data from various hadoop
>> logs in real time using Kafka/Yarn API and uses HDFS and HBase for storage.
>> 2.Data processing and policy engine - Eagle allows users to create
>> policies based on various metadata properties on HDFS, Hive and HBase data.
>> 3.Eagle services - Eagle services include policy manager, query service
>> and the visualization component. Eagle provides intuitive user interface to
>> administer Eagle and an alert dashboard to respond to real time alerts.
>> Data Collection and Storage:
>> Eagle provides programming API for extending Eagle to integrate any data
>> source into Eagle policy evaluation framework. For example, Eagle hdfs
>> audit monitoring collects data from Kafka which is populated from namenode
>> log4j appender or from logstash agent. Eagle hive monitoring collects hive
>> query logs from running job through YARN API, which is designed to be
>> scalable and fault-tolerant. Eagle uses HBase as storage for storing
>> metadata and metrics data, and also supports relational database through
>> configuration change.
>> Data Processing and Policy Engine:
>> Processing Engine: Eagle provides stream processing API which is an
>> abstraction of Apache Storm. It can also be extended to other streaming
>> engines. This abstraction allows developers to assemble data
>> transformation, filtering, external data join etc. without physically bound

>> and joins sensitivity metadata, security zone metadata which are generated
>> from external programs or configured by user. Eagle hive monitoring filters
>> running jobs to get hive query string and parses query string into object
>> and then joins sensitivity metadata.
>> Alerting Framework: Eagle Alert Framework includes stream metadata API,
>> scalable policy engine framework, extensible policy engine framework.
>> Stream metadata API allows developers to declare event schema including
>> what attributes constitute an event, what is the type for each attribute,

>> Extensible policy engine framework allows developer to plugin a new policy
>> engine with a few lines of codes. WSO2 Siddhi CEP engine is the policy

>> 1.Ability to identify and stop security threats in real time

>> 3.Ability to create data access policies

>> 5.Visualize alerts in real time
>> 6.Ability to block malicious access in real time

>> As mentioned in the background, the business requirement and urgency to

>> With the power of open source distributed systems like Hadoop, Kafka and

>> can scale, identify and stop malicious access in real time.
>> Eagle allows admins to create standard access policies and rules for

>> machine learning models for modeling user profiles based on user access
>> behaviour and use the model to alert on anomalies.
>> Current Status

>> Community
>> Eagle seeks to develop the developer and user communities during
>> incubation.
>> Core Developers
>> Eagle is currently being designed and developed by engineers from eBay
>> Inc. – Edward Zhang, Hao Chen, Chaitali Gupta, Libin Sun, Jilin Jiang,
>> Qingwen Zhao, Senthil Kumar, Hemanth Dendukuri, Arun Manoharan. All of
>> these core developers have deep expertise in developing monitoring products
>> for the Hadoop ecosystem.
>> Alignment
>> The ASF is a natural host for Eagle given that it is already the home of
>> Hadoop, HBase, Hive, Storm, Kafka, Spark and other emerging big data
>> projects. Eagle leverages lot of Apache open-source products. Eagle was
>> designed to offer real time insights into sensitive data access by actively
>> monitoring the data access on various data sets in hadoop and an extensible
>> alerting framework with a powerful policy engine. Eagle compliments the
>> existing Hadoop platform area by providing a comprehensive monitoring and
>> alerting solution for detecting sensitive data access threats based on
>> preset policies and machine learning models for user behaviour analysis.
>> Known Risks
>> Orphaned Products
>> The core developers of Eagle team work full time on this project. There is
>> no risk of Eagle getting orphaned since eBay is extensively using it in
>> their production Hadoop clusters and have plans to go beyond hadoop. For
>> example, currently there are 7 hadoop clusters and 2 of them are being
>> monitored using Hadoop Eagle in production. We have plans to extend it to
>> all hadoop clusters and eventually other data platforms. There are 10’s of
>> policies onboarded and actively monitored with plans to onboard more use
>> case. We are very confident that every hadoop cluster in the world will be
>> monitored using Eagle for securing the hadoop ecosystem by actively
>> monitoring for data access on sensitive data. We plan to extend and
>> diversify this community further through Apache. We presented Eagle at the
>> hadoop summit in china and garnered interest from different companies who
>> use hadoop extensively.
>> Inexperience with Open Source
>> The core developers are all active users and followers of open source.
>> They are already committers and contributors to the Eagle Github project.
>> All have been involved with the source code that has been released under an
>> open source license, and several of them also have experience developing
>> code in an open source environment. Though the core set of Developers do
>> not have Apache Open Source experience, there are plans to onboard
>> individuals with Apache open source experience on to the project. Apache
>> Kylin PMC members are also in the same ebay organization. We work very
>> closely with Apache Ranger committers and are looking forward to find
>> meaningful integrations to improve the security of hadoop platform.
>> Homogenous Developers
>> The core developers are from eBay. Today the problem of monitoring data
>> activities to find and stop threats is a universal problem faced by all the
>> businesses. Apache Incubation process encourages an open and diverse
>> meritocratic community. Eagle intends to make every possible effort to
>> build a diverse, vibrant and involved community and has already received
>> substantial interest from various organizations.
>> Reliance on Salaried Developers
>> eBay invested in Eagle as the monitoring solution for Hadoop clusters and
>> some of its key engineers are working full time on the project. In
>> addition, since there is a growing need for securing sensitive data access
>> we need a data activity monitoring solution for Hadoop, we look forward to

>> security space to contribute. Eagle intends to do this.
>> Relationships with Other Apache Products
>> Eagle has a strong relationship and dependency with Apache Hadoop, HBase,
