"Cannot find module 'tough-cookie'" is the same error you get when you are on the wrong C++ compiler version. I would check that again.

When you say you updated gcc at it fixed it, what do you mean? Did you successfully build at one point but now it's failing again? Either way that log statement doesn't tell us much other than which module failed. We would need to look at the full log to see what the root cause is.

I can see a couple different options. You could either move your raw sensor data back home and then replay it through your home metron cluster or you could export the ES indices and HDFS archives and import them into your home cluster. Migrating data from one metron cluster to another is not a common use case and is not something we test. You will likely need to do some research into migrating data between ES/HDFS clusters should you decide to go that route.

Is there any reason you couldn't just route all data to your home base Metron cluster?

You should be able to change the "es.date.format" in the global config to something less granular than each hour. For example, you could change the default of ""yyyy.MM.dd.HH" to ""yyyy.MM.dd" which would cause the indexes to roll every day instead. See this section in the READMEs for more info: https://github.com/apache/metron/tree/master/metron-platform/metron-common#global-configuration.

We are using a Maven plugin that installs specific versions of node and npm locally so I don't think that is it (everyone uses the same version). We have seen build errors before that are related to the C++ compiler version (https://issues.apache.org/jira/browse/METRON-1265). I would try that first. If that doesn't resolve it, we'll need more information from the build logs. Hard to tell what the cause is from what was posted.

When cloning and building Metron locally you have to be careful about adding extra files within your local copy. There is a plugin that runs (Apache Rat) that checks for licenses whenever you build. You likely added some files that don't have license headers and your best bet is to remove the files flagged in /path/to/metron/target/rat.txt.

There is also a metron_rest_classpath parameter that can be used for the same purpose (both of these parameters are added to the REST application classpath). You might want to consider keeping just /path/to/metron-elasticsearch-*-uber.jar in metron_indexing_classpath and moving the others to metron_rest_classpath. Probably won't matter now but could cause issues down the road if metron_indexing_classpath is ever reused for something else.

I am little confused by the term "AWS EC2 users". Do you mean EC2 host? At this point we're just trying to establish that the host is up and accessible. No need to log in to the host (yet). The first step is to verify that the host is actually up. You can find the host status by logging into the AWS console and navigating to the EC2 service. If it is in fact up, security rules may be the cause. Navigate to Network & Security > Security Groups, select the security group for that host and check out the Inbound rules. Assuming you are using our scripts to deploy this (as explained in /incubator-metron/deployment/amazon-ec2/README.md)? May be easier to just start fresh. AWS can be unpredictable sometimes.

Can you verify that you can access Ambari at ec2-52-38-224-98.us-west-2.compute.amazonaws.com:8080? That part of the deployment process is polling that address for a response so the first step is to make sure it's actually available.
