WARNING: Unable to retrieve host 'ITLHost' associated with custom component

Problem:

When I was trying to deploy the CRS app that come with ATG11.1 on my linux box I got the following warning

WARNING: Unable to retrieve host 'ITLHost' associated with custom component 

Solution:

On looking at the Appconfig.xml and related configuration files, I found out that the warning occurred because the definition of ITLHost was happening in DataIngest.xml but it was used in WorkbenchConfig.xml which was imported before DataIngest.xml in Appconfig.xml, see below the CRS Default definition of Appconfig.xml 

  <spr:import resource="InitialSetup.xml" />
  <spr:import resource="DgraphDefaults.xml" />
  <spr:import resource="AuthoringDgraphCluster.xml" />
  <spr:import resource="LiveDgraphCluster.xml" />
  <spr:import resource="LiveAppServerCluster.xml" />
  <spr:import resource="UsageCollectionConfig.xml" />
  <spr:import resource="WorkbenchConfig.xml" />
  <spr:import resource="ReportGeneration.xml" />
  <spr:import resource="DataIngest.xml" />

  <spr:import resource="AssemblerConfig.xml" />

So changing the order of imports as follows, fixed that warning, when I tried to a new endeca deploy. See updated Appconfig.xml below..

  <spr:import resource="InitialSetup.xml" />
  <spr:import resource="DgraphDefaults.xml" />
  <spr:import resource="AuthoringDgraphCluster.xml" />
  <spr:import resource="LiveDgraphCluster.xml" />
  <spr:import resource="LiveAppServerCluster.xml" />
  <spr:import resource="UsageCollectionConfig.xml" />

  <spr:import resource="DataIngest.xml" />

  <spr:import resource="WorkbenchConfig.xml" />
  <spr:import resource="ReportGeneration.xml" />
  <spr:import resource="AssemblerConfig.xml" />
