Re: [geomesa-users] Configuring GeoServer for GeoMesa

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



accumulo-fate.jar (I002)

commons-configuration-1.6.jar (I002)

commons-lang-2.6.jar (I002)


I am continuing with the instruction at


I brought up GeoServer and added a new workspace (name:geomesa, 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/, initiating session

272862 [btpool0-7-SendThread(localhost:2181)] WARN org.apache.zookeeper.ClientCnxn - Session 0x0 for server localhost/, unexpected error, closing socket connection and attempting reconnect

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


Any ideas what might be going wrong here?

I think you will need:


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.

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?
