Hi Adina, These days I'm trying to run Rya in my Ubuntu laptop. Therefore I set up Hadoop, Zookeeper and Accumulo. After a shutdown, I need to restart hadoop, zookeeper and accumulo. But when i do Hadoop and Zookeeper servers are starting successfully but when i initialize Accumulo i get the following, 2016-04-19 16:56:06,984 [fs.VolumeManagerImpl] WARN : dfs.datanode.synconclose set to false in : data loss is possible on hard system reset or power loss 2016-04-19 16:56:06,985 [init.Initialize] INFO : Hadoop Filesystem is hdfs://localhost:9000 2016-04-19 16:56:06,986 [init.Initialize] INFO : Accumulo data dirs are [hdfs://localhost:9000/accumulo] 2016-04-19 16:56:06,986 [init.Initialize] INFO : Zookeeper server is localhost:2181 2016-04-19 16:56:06,986 [init.Initialize] INFO : Checking if Zookeeper is available.

But I think to run Rya there must be a constant instance name as in Rya README.md. I asked help from Accumulo-dev about this problem but I'm unable to find a correct path to solve this. Any idea about this is thoroughly appriciated. Thank you.
