Re: [geomesa-users] Configuring GeoServer for GeoMesa

I think I’ve gotten past the “missing .jar file” issues, adding the following .jars:

 

accumulo-core.jar

accumulo-fate.jar (I002)

commons-configuration-1.6.jar (I002)

commons-lang-2.6.jar (I002)
hadoop-common-2.2.0.jar
hadoop-mapreduce-client-core-2.2.0.jar
libthrift-0.9.0.jar
zookeeper-3.4.2.jar

 

I am continuing with the instruction at http://geomesa.github.io/2014/04/17/geomesa-gdelt-analysis/.

 

I brought up GeoServer and added a new workspace (name:geomesa,url:www.geomesa.org). That went fine.

 

Then I tried to register the GeoMesa data store with GeoServer, defining the “geomesa:gdelt” data store as shown in the tutorial. I used all the same connection parameters I used to ingest the GDELT 20140507 data.

 

However, when I hit “Save” I got the following error on the web-page:

 

Error creating data store, check the parameters. Error message: Failed to connect to zookeeper (localhost:2181) within 2x zookeeper timeout period 30000

 

The GeoServer standard-error output a large number of the following errors (presumably one for each failed attempt to connect to ZooKeeper):

 

272858 [btpool0-7-SendThread(localhost:2181)] INFO org.apache.zookeeper.ClientCnxn - Socket connection established to localhost/127.0.0.1:2181, initiating session

However, as far as I can tell, ZooKeeper is running fine and responded to commands such as “echo ruok | nc 127.0.0.1 5111”.

 

Any ideas what might be going wrong here?

 

Thanks,

Bob,

I think you will need:

accumulo-core.jar
hadoop-common-2.2.0.jar
hadoop-mapreduce-client-core-2.2.0.jar
libthrift-0.9.0.jar
zookeeper-3.4.2.jar

You do not need the geomesa-dist in your geoserver/WEB-INF/lib

We are planning to update the documentation with our next release, thanks for bearing with us in the meantime.

I am trying to configure GeoServer to work with GeoMesa as described in http://geomesa.github.io/2014/04/17/geomesa-gdelt-analysis/.

 

I installed GeoServer and copied the following jar files to $GEOMESA_HOME/webapps/geoserver/WEB-INF/lib:

 

-rw-rw-r--. 1 barnhartr barnhartr 145182720 May  9 10:13 geomesa-dist-1.0.0-SNAPSHOT-distribution.tar

-rw-rw-r--. 1 barnhartr barnhartr   1340305 May 21 10:27 zookeeper-3.4.6.jar

 

However, when I start GeoServer, I’m getting the following exception:

The tutorial says that “Your local Accumulo and Zookeepers JARs also need to be available within your GeoServer’s lib directory.”.

 

The GeoMesa “Getting Started” document also says:

 

Note that you will also need other JAR files, particularly those pertaining to: accumulo-core; hadoop-core; zookeeper; libthrift; and cloudtrace. These are support services that are referenced by GeoMesa, yet are part of your base infrastructure.

 

Which other .jar files are required for GeoServer+GeoMesa and where must they be installed?

 

Thanks,
