BigInsights, docker

Problem
I've spent some time trying to dockerize BigInsights, IBM Open Platform. After resolving some issues, I was able to perform installation. Everything run smoothly except Spark installation. Although installation was reported as successful, Spark History Server did not start.

 File "/usr/lib/python2.6/site-packages/resource_management/libraries/providers/hdfs_resource.py", line 424, in action_delayed
    self.get_hdfs_resource_executor().action_delayed(action_name, self)
  File "/usr/lib/python2.6/site-packages/resource_management/libraries/providers/hdfs_resource.py", line 265, in action_delayed
    self._assert_valid()
  File "/usr/lib/python2.6/site-packages/resource_management/libraries/providers/hdfs_resource.py", line 243, in _assert_valid
    raise Fail(format("Source {source} doesn't exist"))
resource_management.core.exceptions.Fail: Source /usr/iop/current/spark-historyserver/lib/spark-assembly.jar doesn't exist

It turned out that spark-core_4_2_0_0-1.6.1_IBM-000000.el7.noarch.rpm did not unpack all files included. Some directories: /usr/iop/4.2.0.0/spark/lib and /usr/iop/4.2.0.0/spark/sbin were skipped. What is more interesting, while installing the package using rpm command directly, rpm -i spark-core_4_2_0_0-1.6.1_IBM-000000.el7.noarch.rpm, all content of rpm was extracted correctly, while using yum command, yum install spark-core_4_2_0_0-1.6.1_IBM-000000.el7.noarch.rpm, some directories were excluded without signaling any error. I spent sleepless night trying to get a clue.
Solution
I found the explanation here. There was a mistake in spark-core_4_2_0_0-1.6.1_IBM-000000.el7.noarch.rpm package. Some files in the rpm were marked as 'documentation'. It was revealed by running rpm --dump command.

The signature: root root 0 1 0 (mark 1) describes the file as "documentation". To shrink the space consumed by packages, the docker "centos" image contains "tsflags=nodocs" feature in /etc/yum.conf configuration file.
So the temporary workaround is to comment out this feature. To avoid loading unnecessary documentation, one can install Spark separately and have this patch in force only during the installation of this component.
