Hi All,
we have a running hadoop cluster where we unfortunately have a hostname
in uppercase, e.g. SRV-HADOOP01.BIGDATA.LOCAL.
As of Ambari 1.7 we are experiencing a lot of side effects which are
presumably caused by the hostnames in uppercase.
I would like to rename the particular hosts(e.g.
srv-hadoop01.bigdata.local), so that there are only hosts with lowercase
names in the cluster.
Is it possible to change the hostname? I came across a few blogs, but in
general renaming hostnames seems not to be recommended.
Has anyone performed a hostname change?
Many thanks in advance.
