While running the 'cloudera-director bootstrap' command for the cloudera director client we see the following error in the logs while running the 'Installing cloudera-manager-daemons package' step. This exact configuration was used to start a cluster the previous day so this is probably something with the environment but I can't find any indications of what may be the cause.

I am able to manually SSH into the server and try to run the cloudera-manager-daemons installation and I get this output.

Since I know of no changes in our files, I am not sure why the yum / rpm installations from cloudera no longer appear to be working.

After experiencing this for a week it appears to have resolved itself. The most likely root cause for this was networking issues within AWS however we were not able to find anything in our specific instance.

Hi Dustin -

Is this transient? It could a tempoary Cloudera CDN / download site error. Did the AWS environment change in a way that could impact outbound internet access? (new security group rules, network ACLs, NAT instance changes etc.)

It could help to add "yum clean all" to the bootstrap script to make sure there is no stale information.

Dustin · ‎01-06-2016

Andrei,

This was happenning all day yesterday with at least 4 attempts made. I tried again this morning and while it passed the cloudera-manager-daemon step, it failed with basically the same error on the 'Installing cloudera-manager-server' step this time. I am can check with our operations to see if there are any network changes in AWS but I don't think so. I also checked the security group and all traffic is enabled on both inbound and outbound rules.

I will add yum cleanup commands to the end of our custom bootstrap to see if that works.

yum clean all

yum makecache

Thanks

Andrei Savu · ‎01-06-2016

This may also happen due to one of the recent maintainance releases.

Please check the following properties for accuracy:

within the cloudera-manager {} block repository: and repositoryKeyUrl:
within the cluster {} block products {} and parcelRepositories:

Dustin · ‎01-06-2016

Here was our initial configuration: (#1)

no `repository, repositoryKeyUrl, or parcelRepositories` configurations specified in the cloudera-manager block
inside cluster{} -> products{} we had 'CDH: 5' configured

We also tried to update this to a specific version with these configurations: (#2)

only 'parcelRepositories: ' specified as http://archive.cloudera.com/cdh5/parcels/5.3.3/
no `repository or repositoryKeyUrl` configurations specified
inside cluster{} -> products{} we have 'CDH: 5.3.3' configured

Startup Attempts

The first attempt today with configuration #1 was unsuccessful.
Another attempt with conf #1 and adding `yum clean all` and `yum makecache` was successful
We updated to conf #2, keeping the yum commands and we ran into the same error.

I don't think the yum commands made a difference but it would be nice to know what we should specify in the repositories and products configurations to specify a specific version of CDH to install.

Andrei Savu · ‎01-07-2016

This is an example on how you can have strict control over version numbers for all the diferrent components:

cloudera-manager {

    repository: "http://archive.cloudera.com/cm5/redhat/6/x86_64/cm/5.5.1/"
    repositoryKeyUrl: "http://archive.cloudera.com/cm5/redhat/6/x86_64/cm/RPM-GPG-KEY-cloudera"

    [...]
}

cluster {

    products {
      CDH: 5.5.1
    }

    parcelRepositories: ["http://archive.cloudera.com/cdh5/parcels/5.5.1/"]

    [...]
}

It's important that when you override the parcel version you also change Cloudera Manager repository to be in sync. Older versions of Cloudera Manager do not support newer versions of CDH and in some cases you may get hard to debug non-determistic failures.

Do you have a NAT instance in your environment? Could that be affected by high load?

Dustin · ‎01-08-2016

Based on your response we were able to get a specific version of the cluster created. We are still experiencing about a 50% failure rate when installing however. If we can confirm there are no issues on cloudera's end then we will have to start looking into issues with the AWS accounts NAT.
