About Tutorial Versions¶

The tutorials listed in this manual can be obtained from GitHub, by cloning the geomesa-tutorials project:

$ git clone https://github.com/geomesa/geomesa-tutorials.git
$ cd geomesa-tutorials

Keep in mind that you may have to download a particular release of the tutorials project to match the GeoMesa version that you are using. For example, to target GeoMesa 1.3.5, you should download version 1.3.0.0-m2 of the geomesa-tutorials project ($TUTORIAL_VERSION = 1.3.0.0-m2):

$ git checkout geomesa-tutorials-$TUTORIAL_VERSION

In general, the major, minor, and patch version numbers of the tutorials release will match the corresponding numbers of the GeoMesa version. The tutorials version contains a fourth digit number permitting multiple releases per GeoMesa release.

You may also see the geomesa-tutorials releases available, and download a tarball of a release on the geomesa-tutorials releases page.

Hadoop Version¶

Most of the tutorials encourage you to update the pom.xml to match the versions of the services you are using (Hadoop, ZooKeeper, Accumulo, etc.) However, there may be issues when incrementing the Hadoop version to 2.6 or above, which can result in Apache Curator version conflicts. Leaving the Hadoop version set to 2.2 in the tutorials pom.xml will work with all subsequent Hadoop 2.X releases.
