> *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.
