Can you elaborate on how they don't exist? Do you mean you have errors
about files not being found for your table or every time you start Accumulo
it's like the first time?

I don't get any errors.  The tables just don't exist anymore, as if I were
starting accumulo for the first time.

Have you changed the default zookeeper temp directory away from /tmp?

Do you mean "dataDir" in the zoo.cfg file?  I changed that from
"/tmp/zookeeper" to "/var/zookeeper"

Are you just doing stop-all.sh and then start-all.sh? Or are you running
other commands?

I'm running these commands to start :

/opt/hadoop/bin/start-all.sh
/opt/zookeeper/bin/zkServer.sh start
/opt/accumulo/bin/accumulo init
/opt/accumulo/bin/start-all.sh
/opt/accumulo/bin/accumulo shell -u root

and these commands to stop :

/opt/hadoop/bin/stop-all.sh
/opt/zookeeper/bin/zkServer.sh stop
/opt/accumulo/bin/stop-all.sh

accumulo init is used to initialize the instance. are you running that
every time?

though it should error because you already have an instance, perhaps not
setting the dfs.data.dir AND initializing it might cause the error

So i changed the dfs.data.dir and dfs.name.dir and tried to re-start
accumulo.

On running this command : "/opt/accumulo/bin/accumulo init" I get the
following error :

If you change the name dir I think you need to reformat the namenode.

Hey all,

I have a problem with my Accumulo tables deleting upon shutdown.  I
currently have Accumulo, Zookeeper, and Hadoop in my /opt directory.  I'm
assuming that somehow my tables are being placed in a tmp directory that
gets wiped when I shut my computer off.  I'm trying to develop and test on
my local machine.

What should I change in the conf files or otherwise in order to ensure that
the tables are not destroyed on shutdown?

Thanks

You need to change the hdfs configuration file in $HADOOP_HOME/conf

The properties are dfs.data.dir and dfs.name.dir

Doesn't HDFS use /tmp by default to store its data?
You may want to update your ${HADOOP_HOME}/conf/hdfs-site.xml file to
specify a different location.

Your hdfs isn't online. Specifically, you have no running datanodes. Check
the logs to figure out why it's not coming online and remedy that before
initializing Accumulo.

Sent from my phone, so pardon the typos and brevity.

Jonathan,

When you reformat the name node, you also need to wipe out the data node
directories. Otherwise they will complain about the name node ID being
wrong. You can find that message in the HDFS datanode logs.

Generally, it's a good idea to run checks on Zookeeper and HDFS independent
of Accumulo, just to make sure the dependencies are up and running
properly. $ZOOKEEPER_HOME/bin/zkCli.sh gives you commandline access to
Zookeeper that you can test it with (e.g. connect to it, write a node, read
a node, delete a node), and "hadoop fs" provides the same for HDFS. The
monitor page for hdfs (http://MASTER_NODE:50070) can also give you some
assurances that HDFS is working properly.

Cheers,
Adam
