MapR Installer Verification fails on all nodes

I am trying to install MapR Distribution 5.2.2 with MEP 3.0.1 and some additional Custom Servies (see attached services.png). At the Verification step the nodes don't verify (see attached verfication.txt).


We had an old MapR Version on the nodes that could not be updated as the installer database got corrupted and could not be rescued with stanzas etc. . First I followed all guides to uninstall MapR from a Node that I could find (see Word Document if interested). Then I followed the ADM2000 Guide of the MapR Academy and you can find the logs of the pre install tests attached. This also provides Information about the system. For Example:



Disk /dev/sda: 21.5 GB, 21474836480 bytes
Disk /dev/sdb: 322.1 GB, 322122547200 bytes

MemTotal:       16384 MB

Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz


I can't really read anything from the verfication.txt Log that the installer provides. I also attached the installer logs and couldn't find anything in MapR Installation Troubleshooting Guide.


Kind regards,



P.S. Node Verification Failure during MapR Installation sadly didnt have an answer.
