An update:
* Parallel tests for Hadoop have been turned on. I missed that
HDFS-9139 enabled them globally.
* The bug preventing Docker mode has been fixed and now enabled. Note
that this will likely hide broken tests that misuse ports...
* We’re using Yetus’ default Docker image so the JDKs are now Oracle
JDK 1.8.0_60 and OpenJDK 1.7.0_79. Oracle JDK 1.8.0_80 is also available.
Lots of other binaries are installed and upgraded as well (e.g., shell check),
so test coverage will improve.
