NOTE: In the examples that follow, user details, table name, company name, email, hostnames, etc. represent a fictitious sample (and are used to provide an illustrative example only). Any similarity to actual persons, or entities, living or dead, is purely coincidental and not intended in any manner.

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.

Known issues

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.

2. Node reprovision fails at Step 3, PatchFactoryImage with errors like:
