Accumulo Clients in Other Programming Languages
Date: 16 Dec 2019
Apache Accumulo has an Accumulo Proxy that allows communication with Accumulo using clients written in languages other than Java. This blog post shows how to run the Accumulo Proxy process using Uno and communicate with Accumulo using a Python client.
First, clone the Accumulo Proxy repository.
git clone https://github.com/apache/accumulo-proxy
export POST_RUN_PLUGINS="accumulo-proxy" export PROXY_REPO=/path/to/accumulo-proxy
Run the following command to set up Accumulo again. The Proxy will be started after Accumulo runs.
uno setup accumulo
After Accumulo is set up, you should see the following output from uno:
Executing post run plugin: accumulo-proxy Installing Accumulo Proxy at /path/to/fluo-uno/install/accumulo-proxy-2.0.0-SNAPSHOT Accumulo Proxy 2.0.0-SNAPSHOT is running * view logs at /path/to/fluo-uno/install/logs/accumulo-proxy/
Next, follow the instructions below to create a Python 2.7 client that creates an Accumulo table
pythontest and writes data to it:
mkdir accumulo-client/ cd accumulo-client/ pipenv --python 2.7 pipenv install thrift pipenv install -e /path/to/accumulo-proxy/src/main/python cp /path/to/accumulo-proxy/src/main/python/basic_client.py . # Edit credentials if needed vim basic_client.py pipenv run python2 basic_client.py
Verify that the table was created or data was written using
uno ashell or the Accumulo monitor.
