Metron Storm Worker Hostname Issues

avatar
Rising Star

I have Metron deployed on a single node on AWS. Recently had to update the hostname to use AWS private DNS instead of the public DNS (which changes with each reboot). I think I have got most of the services working after the update but I have still have some issues with Storm. A sample of the storm worker logs are copied below. In particular, the o.a.h.i.Client seems to be still referring to the old public EC2 domain name but I have been unable to figure out where that config is specified. Could someone assist in pointing me to where that particular variable is stored?

Ok turns out that core-site.xml, hbase-site.xml and hdfs-site.xml are embedded in the metron jars at /usr/metron/0.2.0BETA/lib so needed to update the hostname references in those files to get it working again.
