ERROR (38) -  RPC to execute 'DISK_LIST' on node: $nodename returned no data.

CauseThis is a new requirement in MapR v3.1. Pre-v3.1 disk information was obtained using SSH to connect to the host and then executing /opt/mapr/server/disklist.sh.  In v3.1 SSH is no longer required to obtain this disk information. A Remote Procedure Call request is now sent to the hoststats service on the remote node over port TCP1111 to retrieve the disk listing. Therefore, any MapR nodes that have been upgraded from pre-v3.1 (Security Analytics 10.3.2 or older) will not have the iptables rule to accept incoming traffic on port TCP 1111.
ResolutionAdd a rule to all MapR nodes to accept incoming traffic on port TCP 1111 
 
#iptables -I INPUT  -p tcp -m state --state NEW -m tcp --dport 1111 -j ACCEPT
#service iptables save
