Re: [geomesa-users] StatsCombiner

Thank you Jim.

 

I followed the instructions for setting up Accumulo namespace to install the distributed runtime jar within HDFS as per the instructions here http://www.geomesa.org/documentation/user/installation_and_configuration.html#installing-the-accumulo-distributed-runtime-library

 

However, I am still getting these errors, although it doesn’t appear on ingest any more, but it is happening on my querying it appears. But I am sure I am querying using 1.2.3 so it should be compatible. Isn’t installing this runtime library equal to deploying the iterators? Or is there something I am missing. I have also removed all jar files from the Accumulo lib/ext path so these should not be getting in the way. But what do I do about old tables that were ingested using an older version of geomesa? Will I need to re-ingest these? With namespaces, in the future I should simply have to specify the table with the namespace prefix and all should be well, but all my old tables were ingested without the use of namespaces.

 

Finally, I am also seeing another strange thing with version 1.2.3. I have an application that creates an AccumuloDataStore object and when the application ends, it doesn’t shut down. It just stays open. I have narrowed it down to the data store object. If I revert back to 1.2.1 this does not happen (I skipped from 1.2.1 to 1.2.3).

 

Cheers,

Nathan

Hi Nathan,

GeoMesa 1.2.3 has the ability to gather stats on the data during ingest.  In order to do this, the StatsCombiner is configured on any new tables (assuming you don't turn the collectStats flag off). 

You should just have to deploy the GeoMesa 1.2.3 iterators on your Accumulo classpath (or on a namespace's classpath).

Generally, during an update, the GeoMesa code for ingest clients, Accumulo iterators, and query clients (like GeoServer) all should match.  Since coordinating that may be complicated, I'd call attention to Accumulo namespaces; I've used namespaces like geomesa120, geomesa121, etc. to help keep things straight on our internal dev cluster.

Cheers,

Jim

Hi. I am trying to upgrade to Geomesa 1.2.3

 

I have a program which does some data ingest using a FeatureWriter. When I try ingesting, I get the following error java.lang.ClassNotFoundException: org.locationtech.geomesa.accumulo.data.stats.StatsCombiner

 

Is there something new I need to be adding to my pom file or something?

 

I have been playing around with this for a while and can’t figure it out.

 

Thanks,

Nathan
