> --------------------------------------------------------------------------------
>
> Key: AMBARI-18404
> URL: https://issues.apache.org/jira/browse/AMBARI-18404
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.4.0
> Reporter: Jonathan Hurley
> Assignee: Jonathan Hurley
> Priority: Critical
> Fix For: 2.4.2
>
>
> When creating an upgrade, the {{upgrades_summary}} endpoint sometimes returns
> a NPE.
> STR:
> - Start an upgrade
> - Force an error (remove {{hdp-select}})
> - Wait for error in upgrade, and then make a request to {{upgrades_summary}}
> {code}
> HostRoleCommandEntity mostRecentFailure =
> s_hostRoleCommandDAO.findMostRecentFailure(upgradeRequestId);
> {code}
> And its requestId is null
> DB is fine
> {code}
> ambari=> select request_id, task_id, status, role, role_command,
> custom_command_name from host_role_command where task_id = 504;
> request_id | task_id | status | role | role_command |
> custom_command_name
> ------------+---------+------------------+-------------+----------------+---------------------
> 45 | 504 | HOLDING_TIMEDOUT | NODEMANAGER | CUSTOM_COMMAND | STOP
> (1 row)
> {code}
> Problem is with query,
> {code}
> TypedQuery<HostRoleCommandEntity> query =
> entityManagerProvider.get().createNamedQuery(
> "HostRoleCommandEntity.findTasksByStatusesOrderByIdDesc",
> HostRoleCommandEntity.class);
> query.setParameter("requestId", requestId);
> query.setParameter("statuses",
> HostRoleStatus.STACK_UPGRADE_FAILED_STATUSES);
> List<HostRoleCommandEntity> results = query.getResultList();
> ...
> HostRoleCommandEntity candidate = results.get(0);
> {code}
> since "candidate" has no requestId.
> However, HostRoleCommandEntity.java defines the query like so,
> {code}
> @NamedQuery(name = "HostRoleCommandEntity.findTasksByStatusesOrderByIdDesc",
> query = "SELECT task FROM HostRoleCommandEntity task WHERE task.requestId =
> :requestId AND task.status IN :statuses ORDER BY task.taskId DESC"),
> {code}
> so the "task" object should have a request_id, especially since it's defined
> to be non-nullable,
> {code}
> @Column(name = "request_id", insertable = false, updatable = false,
> nullable = false)
> @Basic
> private Long requestId;
> {code}
