Data Fabric Development Environment not starting

[glennflaten]

Hi,

I tried to run the Data Fabric Development Environment on Mac. 

Running the Development Environment Script (hpe.com)

Following the steps, the docker container starts. But when I go into the container with ssh rot@localhost -2222 and look in the /opt/mapr/logs/warden.log file it says: 
Warden started
In sysVol
head: cannot open '/opt/mapr/conf/mapr-clusters.conf' for reading: No such file or directory

It seems that the mapr-cluster.conf file doesn't exists and it needs it.

Regards
Glenn

I tried reproducing this but the Docker image appears to be working for me.

# wget https://raw.githubusercontent.com/mapr-demos/mapr-db-720-getting-started/main/mapr_devsandbox_container_setup.sh
# chmod +x mapr_devsandbox_container_setup.sh
# ./mapr_devsandbox_container_setup.sh -nwiterface ens192

Wait 10 minutes

I'm wondering if you were checking the state of the cluster while the configure.sh script was still running?  That script is what configures the cluster services, the storage pool, etc.  

[glennflaten · Accepted solution]

I still get this, but I found the cause. In the script mapr_devsandbox_container_setup.sh on line 96 it runs

sudo /opt/mapr/server/configure.sh -c -C ${IP} -N ${clusterName} > /dev/null 2>&1

When I run that on my Mac M1 i get:

ERROR: install homebrew - run brew install bash and add export PATH=........

So, it is on my side and my installation.
