Hi Tao,
Can you run the following API call from the Ambari Server host?
Please replace the hostnames and jdk_location appropriately.
curl -i -uadmin:admin -H 'X-Requested-By: ambari' -d '{
"RequestInfo": {
"action": "check_host",
"context": "Check host",
"parameters": {
"check_execute_list": "host_resolution_check",
"hosts": "c6401.ambari.apache.org, c6402.ambari.apache.org,
c6403.ambari.apache.org",
"jdk_location":"/usr/jdk64/jdk1.7.0_67",
"threshold": "20"
}
},
"Requests/resource_filters": [
{
"hosts":
"c6401.ambari.apache.org,c6402.ambari.apache.org,c6403.ambari.apache.org"
}
]
}' http://localhost:8081/api/v1/requests
After you make the call, you will get a response like:
{
"href" : "http://localhost:8081/api/v1/requests/32";,
"Requests" : {
"id" : 32,
"status" : "InProgress"
}
}
Note the "id", and make the following call (replace id 32 with the actual id
you get):
curl -i -u admin:admin
http://localhost:8080/api/v1/requests/32/tasks?fields=Tasks/*
Keep calling the above call until the checks complete.
You should be able to see what went wrong.
I hope this helps,
Yusaku

Subject: (Host Checks) Hostname Resolution Issues
Hi all,
I am trying to create a stack through Ambari Web "install wizard". At step
"Confirm Hosts", all nodes pass "registration", but one node reports "Hostname
Resolution Issues", with this detailed report:
######################################
# Hostname Resolution
#
# A newline delimited list of hostname resolution issues.
######################################
HOSTNAME RESOLUTION ISSUES
vm-galaxy03.aware.com could not resolve: .
I do not see any difference between this node (vm-galaxy03.aware.com) and
others. Could any one help?
Thanks,
-Tao
