When a lily web server is in place it usurps the default BDA apache httpd web server and causes node upgrade/migration/reprovision failures. Remove the lily web server prior to BDA upgrade or BDA node migration/reprovison Mammoth actions.
1. Node migration may fail at Step 9, InstallHadoop with logs on the Mammoth node showing errors like below. This can happen in the case of a broken rpm repository. For example if "yum clean all" has been used to clear the cache on a particular server, the lily web server prevents bda rpm updates on the node and these errors can ensue.
yum.Errors.RepoError: Cannot retrieve repository metadata (repomd.xml) for repository: bda.
Please verify its path and try again
2. Node reprovision fails at Step 3, PatchFactoryImage with errors like:
change from absent to latest failed:
Could not update: Execution of '/usr/bin/yum -d 0 -e 0 -y list ota4h' returned 1:
Error: Cannot retrieve repository metadata (repomd.xml) for repository bda. Please verify its path and try again.
Error : (//bdanode01.example.com//Stage[main]/Miscsetup::Patch_fimage/Package[bda]/ensure)
change from 4.2.0-3,el6 to latest failed:
3. After Node reprovision Oracle Linux is not upgraded.
Check for use of the lily web server
1. Download the repomd.xml file and check for the presence of lily.
