Hi Maxim, Rya uses an Accumulo client. The Accumulo client is dependent on Hadoop, particularly HDFS and zookeeper. The environment variable HADOOP_HOME or corresponding property is required to find the path to the locally installed hadoop runtime files. Details can be found in the Accumulo manual where it describes running client code:
