Accumulo Service

The Accumulo service is an administrator utility that provides a rest API which exposes a small subset of Accumulo's table and security operations to external clients. Users must possess the Administrator role to access the service's endpoints.

Getting Started

1. First, refer to services/README for launching the config, authorization, and audit services.

   • The authorization service should be launched with the mock profile to leverage test PKI materials and associated user configuration (see authorization-mock.yml).

2. Launch this service as follows, with the remoteauth profile to enable client cert authentication, and with the mock profile to utilize an in-memory Accumulo instance containing some test data...

   java -jar service/target/accumulo-service*-exec.jar --spring.profiles.active=dev,remoteauth,mock
   

3. Ensure that the testUser.p12 (password: ChangeIt) cert is imported into your browser, and then visit any of the following:

   • https://localhost:8943/accumulo/v1/lookup/warehouseTestTable/row1?colFam=cf1
   • https://localhost:8943/accumulo/v1/lookup/warehouseTestTable/row1?colFam=cf1&useAuthorizations=A,B,C
   • https://localhost:8943/accumulo/v1/lookup/warehouseTestTable/row1?colFam=cf1&useAuthorizations=A,D,E
   • https://localhost:8943/accumulo/v1/lookup/warehouseTestTable/row1?colFam=cf1&useAuthorizations=A,F,G
   • https://localhost:8943/accumulo/v1/admin/listTables
   • https://localhost:8943/accumulo/v1/admin/listUsers
   • https://localhost:8943/accumulo/v1/admin/listUserPermissions/root
   • Perform PUT and POST API operations with your preferred HTTP client, as desired

   Note: The stats API is not functional when using the mock profile, as it requires that ZooKeeper and Accumulo Monitor instances are running

   See sample_configuration/accumulo-dev.yml and configure as desired
