Description

STR:

• Install cluster;
• Go to HDFS config tab
• Click "Save" button (even without any config changes)

Actual result:

• Restart indicators shown near HDFS and Mapreduce services (see screenshot 1), even if there were NOT any config changes;

Expected result:

• When there were some config changes: restart indicator should be shown near HDFS service (see screenshot 2);
• When there were NOT some config changes: restart indicator should NOT be shown near any services;

Described situation reproduced only after first "Save" button click. After required services restart and next some config changes there always expected result.
