Re: [geomesa-users] Unsupported major.minor version 52.0
Hi,

I upgraded java to java 8 and everything works fine now.

Thanks,

José

Hi José,

That means that you are running an older java version. GeoMesa requires java 8.

Thanks,

Emilio

Hi,

I have set up a new Hadoop cluster using the HDP distribution version 2.5.3.0-37. I have downloaded Geomesa Hbase version 2.11-1.3.0, running on HBase version 1.1.2.2.5.3.0-37.

After having launched 'geomesa-hbase configure' and set up the HADOOP_HOME and HBASE_HOME variables on the geomesa-env.sh, I check the installation running 'geomesa-hbase' and I get the following error :

Using GEOMESA_HBASE_HOME = /opt/geomesa-hbase_2.11-1.3.0

I had previously installed Geomesa HBase in another cluster with HDP version 2.4.3.0-227 and running over HBase 1.1.2.2.4.3.0-227 and I never got this problem.

Are there any known incompatibilities with the HDP version 2.5.3.0-37 ? Any idea to solve this problem ?

Thanks again.

José.
