Hi Milan,
Nice, glad you're making progress. They quickstart error you're
seeing is due to a mismatch in versions - try checking out the
'tags/geomesa-1.2.2' branch of that project.
Thanks,
Emilio

Thank you Emilio,
fs.defaultFS is set up to localhost:9000, when I changed this in
the namespace configuration, example ingest seems to work normaly.
I tried to compile and run
geomesa-tutorials/geomesa-quickstart-accumulo, but when I run:
java -cp
geomesa-quickstart-accumulo/target/geomesa-quickstart-accumulo-1.2.3-SNAPSHOT.jar
com.example.geomesa.accumulo.AccumuloQuickStart -instanceId
geomesa -zookeepers localhost:2181 -user geomesa -password geomesa
-tableName geomesa.quickstart_accumulo
I get following error:

Hi Milan,
You probably just need to change the 'localhost' portion of you
jar path with the appropriate namenode. You might be able to
determine it with the following command, although I'm not sure
if it will work exactly with hadoop 2.7:
hdfs getconf -confkey 'fs.defaultFS'
Make sure that the port is correct as well.
Thanks,
Emilio

Hello Emilio,
Thank you for quick response.
I am running following environment:
Ubuntu Server 14.04
java-7-openjdk-amd64
accumulo 1.6.5
hadoop 2.7.2
zookeeper 3.4.8
geomesa 1.2.2
All is installed on one server
I have installed accumulo, hadoop and zookeeper according to
this tutorial:
https://www.digitalocean.com/community/tutorials/how-to-install-the-big-data-friendly-apache-accumulo-nosql-database-on-ubuntu-14-04
When I used ./hadoop fs -ls
'hdfs://localhost:54310/accumulo/classpath/geomesa/geomesa-accumulo-distributed-runtime-1.2.2.jar'
I get following:
ls: Call From geomesa/127.0.0.1 to localhost:54310 failed on
connection exception: java.net.ConnectException: Connection
refused; For more details see: http://wiki.apache.org/hadoop/ConnectionRefused
I copied geomesa-accumulo-distributed-runtime-1.2.2.jar using
./hadoop fs -copyFromLocal
geomesa-accumulo-distributed-runtime-1.2.2.jar
/accumulo/classpath/geomesa
Sorry, I am very new to accumulo, hadoop etc.
thank you,
Milan

Hi Milan,
It seems like Accumulo can't find your jar in HDFS. What
version of Accumulo are you running on? The namespace
configurations are only available on 1.6 and later. Also,
what is the namenode of your hdfs setup? It it set to
localhost in your error. Does that path work using the
'hadoop' command? e.g. hadoop fs -ls '
hdfs://localhost:54310/accumulo/classpath/geomesa/geomesa-accumulo-distributed-runtime-1.2.2.jar'.
Also, ensure that the jar is actually there in HDFS.
Let us know if none of that works.
Thanks,
Emilio

Dear sir / madam,
We would like to evaluate geomesa as one of the most
promising technologies in our company. I have a problem
with right setup.
When I installed geomesa bin according to http://www.geomesa.org/documentation/user/installation_and_configuration.html
When I run Ingesting data example, I get this error
message in Accumulo:
could not determine file type
hdfs://localhost:54310/accumulo/classpath/geomesa/geomesa-accumulo-distributed-runtime-1.2.2.jar
I get the same error also when I run Accumulo quick start.
I would also like to ask, how should I set up GeoTools for
Geoserver, What modules from geotools are needed for
geoserver in order to be able to use geomesa datastore ?
Thank you,
Milan
