---------------------------------
Thanks [~xkrogen]. Will address the issues. In the style issues though:
{code}
./hadoop-common-project/hadoop-common/src/test/java/org/apache/hadoop/ha/DummyHAService.java:59:
boolean failToBecomeActive, failToBecomeStandby, failToBecomeObserver,:11:
Variable 'failToBecomeActive' must be private and have accessor methods.
[VisibilityModifier]
./hadoop-common-project/hadoop-common/src/test/java/org/apache/hadoop/ha/DummyHAService.java:59:
boolean failToBecomeActive, failToBecomeStandby, failToBecomeObserver,:31:
Variable 'failToBecomeStandby' must be private and have accessor methods.
[VisibilityModifier]
./hadoop-common-project/hadoop-common/src/test/java/org/apache/hadoop/ha/DummyHAService.java:59:
boolean failToBecomeActive, failToBecomeStandby, failToBecomeObserver,:52:

./hadoop-common-project/hadoop-common/src/test/java/org/apache/hadoop/ha/DummyHAService.java:60:
failToFence;:7: Variable 'failToFence' must be private and have accessor
methods. [VisibilityModifier]
{code}
This might be more involved and is not so related to this JIRA. Should we leave
them as it is for now?
