DataStax Academy migrated to a new learning management system (LMS) in July 2020. We are also moving to a new Cassandra Certification process so there are changes to exam bookings, voucher system and issuing of certificates.
Check out the Academy FAQ pages for answers to your questions:
The DSE 6.0 tarball is a compressed archive so you also need to specify the unzip flag (
-z) in the command.
Here is the correct command to unpack the tarball:
$ tar xzf dse-6.0.0-bin.tar.gz
In some cases the downloaded tarball may also be corrupted so if you are still having issues unpacking it, verify the file type and compare the checksum against these:
$ file dse-6.0.0-bin.tar.gz dse-6.0.0-bin.tar.gz: gzip compressed data, from FAT filesystem (MS-DOS, OS/2, NT)
$ cksum dse-6.0.0-bin.tar.gz 3517560460 911703665 dse-6.0.0-bin.tar.gz
In addition, validate the OVA file you downloaded against this checksum:
$ cksum DS201-VM-6.0.ova 535688765 2881041408 DS201-VM-6.0.ova
It is unlikely that the VirtualBox image would be corrupted given that you have successfully imported it already but I've mentioned it here for completeness.
If any of the above don't match, it will confirm that your copy is corrupted and you will need to download them again. Cheers!
