while cluster is installed with uppercase hostnames.
[ https://issues.apache.org/jira/browse/AMBARI-14453?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Dmitry Lysnichenko updated AMBARI-14453:
----------------------------------------
Description:
Steps followed -
1. Hadoop cluster with below config is installed successfully with uppercase hostnames.
{code}
CLUSTERNAME='N91'
MASTER1=N9-1-1.labs
MASTER2=N9-1-2.labs
DATANODE1=N9-1-3.labs
DATANODE2=N9-1-4.labs
DATANODE3=N9-1-5.labs
{code}
Snippet of /etc/hosts file -
{code}
10.0.8.1 N9-1-1.labs N9-1-1 byn001-1 hadoopvm1-1
10.0.8.2 N9-1-2.labs N9-1-2 byn001-2 hadoopvm1-2
10.0.8.3 N9-1-3.labs N9-1-3 byn001-3 hadoopvm1-3
10.0.8.4 N9-1-4.labs N9-1-4 byn001-4 hadoopvm1-4
10.0.8.5 N9-1-5.labs N9-1-5 byn001-5 hadoopvm1-5
{code}
2. Ambari host page shows all hostnames to be of lower case.
3. Attempt to run jobs fails on -
