  Hi,

  Ideally,with co-located clusters, Vertica is installed on some or all of your Hadoop nodes. The Vertica nodes should use a "private network" in addition to the "public network" used by all Hadoop nodes...

  See:

  Hello Jim , Thank you for suggesting it. Actually we have installed Hortonworks 2.5.3 and vertica 9 on 3 nodes. Hadoop using 3 nodes ( 1 name node , 2 data nodes) , On the same 3 nodes we have install vertica 9 . For it we create two Ethernet ports etho ( used by Hadoop) and eth1 (used by Vertica) . These all are VMs on a single machine. IP address of nodes are like
  etho - 15.153.155.120 --- Hadoop
  eth1 - 15.153.155.102 ---- Vertica
  like for other nodes.
  Broadcast ip and Mask ip are same for both.

  The issue what we are facing is on which node we have created name node and one vertica instance is getting disconnected from out side ( putty) suddenly 3-4 times in a day.
  Node is up , but not accessible from putty, then Infra. team use to restart network services or some times it comes up automatically.

  What can be the issue , Is our ip configuration is correct.

  Thanks

  Hi,

  Usually if a client (i.e. Putty) gets disconnected its a network timeout of some sort.

  Check the following threads to see if they help:

  I don't think its a timeout issue.

  Node is up , but not accessible from putty, then Infra. team use to restart network services or some times it comes up automatically.

  @rohitmathur10
  Looks like a problem in VM host machine, not with Vertica or Hortonworks. Host machine is Linux or Windows? I faced similar issue with Windows 10(wrong IP mapping).

  Yeah, could be the VM! I've seen IP addresses disappear on a VM I wonder if after putty loses it connection if that server can even be pinged or connected to via telnet anymore. Probably not.
