--------------------------------------------
Summary: Installing custom service hangs at install step for 15-20
mins when having to install dependencies.
Key: AMBARI-22456
URL: https://issues.apache.org/jira/browse/AMBARI-22456
Project: Ambari
Issue Type: Bug
Affects Versions: 2.5.0, 2.6.0
Environment: CENTOS7, RHEL7
Reporter: Christopher Jackson
When installing a custom service that has a client component that has several
dependencies on clients of other services, for example:
```
<dependency>
<name>HDFS/HDFS_CLIENT</name>
<scope>host</scope>
<auto-deploy>
<enabled>true</enabled>
</auto-deploy>
</dependency>
```
the installation step in the install service wizard hangs for several minutes
(10-20mins) while it installs all those clients on the various nodes in the
cluster. The UI reports `Preparing to install <custom service client name>`
and sits at 0% until all the dependency clients are installed. Once the
dependencies are installed progress begins on installing the components of the
custom service and the UI shows progress correctly.
I would not expect this behavior. I would expect the UI to report that it is
making progress installing the clients that are dependencies so that it does
not appear that the installation has hung.
