> Host Components stuck in Installing state
> -----------------------------------------
>
> Key: AMBARI-4621
> URL: https://issues.apache.org/jira/browse/AMBARI-4621
> Project: Ambari
> Issue Type: Task
> Components: controller
> Affects Versions: 1.5.0
> Reporter: Siddharth Wagle
> Assignee: Siddharth Wagle
> Fix For: 1.5.0
>
>
> *Steps to reproduce:*
> # Start 10 node cluster.
> # On Step-9 of installer wizard while ongoing install command, Stopped
> ambari-agent on 9 hosts.
> # Hit Retry button.
> # Some of the host_components ended up in INSTALL_FAILED state, some in
> UNKNOWN state and others in INSTALLING state. Host components in INSTALLING
> state never transitioned to any other state.
> *Reason*:
> The _ActionScehduler.doWork()_ depends on the HostRoles to timeout before
> aborting the operation in order to update Host Component status.
> This particular issue is caused by a the timing of the change in Host state
> to UNKNOWN, which happens after processing of in progress stages and before
> Abort.
