> When hosts are being mapped to a clusters (see
> ClustersImpl.java:mapHostToCluster) it verifies if the OS type of the host
> matches the OS types supported by the stack that is being deployed.
> If the OS type of the host is not supported than a warning message is logged
> and an exception is thrown which is silently swallowed.
>

>     ....
>     if (!isOsSupportedByClusterStack(cluster, host)) {
>           String message = "Trying to map host to cluster where stack does not"
>               + " support host's os type" + ", clusterName=" + clusterName
>               + ", clusterStackId=" + cluster.getDesiredStackVersion().getStackId()

>           LOG.warn(message);
>           throw new AmbariException(message);

> This message should be logged as ERROR to make easier troubleshooting as most
> of the time people search for exceptions and ERRORs in the log when looking
> into issues with cluster.
