-------------------------------------
Summary: Fix native and management pack cluster installation and
startup
Key: AMBARI-26671
URL: https://issues.apache.org/jira/browse/AMBARI-26671
Project: Ambari
Issue Type: Bug
Reporter: Jialiang Cai
h2. Problem
Native cluster installation with local packages can fail at multiple stages even
when the same component artifacts are deployable through Blueprints:
* optional stack values and significant file-template whitespace are rejected;
* registered repository versions are omitted or their numeric definition IDs are
treated as version strings and stack identities;
* manual registration recovery retains an unused SSH-key requirement;
* standalone stacks are incorrectly required to select HDFS;
* initial host configuration publication can dereference a missing previous
cluster cache; and
* service checks without explicit role-command ordering can run before their own
service daemons have started.
These failures affect both ordinary BIGTOP cluster installation and services
activated through the management-pack store.
h2. Expected behavior
The installer should preserve required validation while accepting declared
optional values and file templates, resolve registered definitions using their
version and stack fields, support standalone non-HDFS stacks, recover manual
registration without SSH credentials, publish an initial authoritative agent
configuration, and order an undeclared service check after that service's daemon
starts without changing explicit dependencies.
h2. Proposed scope
Align the React installer with the documented Classic behavior, add focused
frontend, Python, and Java regression coverage, and retain structured recovery
and operation identity checks. The change does not add new services or rebuild
big-data component packages.
h2. Validation
Focused React suites, stack advisor tests, Java regression tests, and production
frontend builds pass. Live local-package acceptance covers a three-host BIGTOP
cluster, a standalone PostgreSQL management-pack cluster, and a second isolated
BIGTOP cluster. The full project test suite has not been run.
