2011-03-16 18:20:03,021 ERROR [main] [net.sf.ehcache.Cache] <clinit> Unable to set localhost. This prevents creation of a GUID. Cause was: <hostname>: <hostname>
java.net.UnknownHostException: <hostname>: <hostname>
at java.net.InetAddress.getLocalHost(InetAddress.java:1354)
at net.sf.ehcache.Cache.<clinit>(Cache.java:145)
Cause
The local hostname (or COMPUTERNAME - Windows) that is running JIRA is not in the host file or is not resolvable via DNS lookup.
Resolution
Change the local hostname (or COMPUTERNAME in Windows) that is running JIRA to match the host file, or enter the local hostname into the hosts file.
windows
C:\Windows\System32\drivers\etc\hosts
linux/unix environments
/etc/hosts
ℹ️ We strongly recommend placing the hostname in the host file as fail-safe for DNS server failure.
Alternatively, make the hostname resolvable via DNS.
