Getting access

User must be authorized to NXCALS services before accessing data. Request access can be performed using CCDE form which will generate email to NXCALS support team.

TESTBED and PRO environments are targeting the NXCALS production Hadoop cluster (running CERN's Hadoop distribution - with patches for known Apache Hadoop issues).

The cluster is fully managed by IT's Hadoop team (IT-DA-DS) and the user must be registered on it-hadoop-nxcals-pro-analytics e-group, in order to get access to it.

You can self-subscribe there by selecting "members" tab and clicking on "Add me" button.
