Jean-Marc Spaggiari commented on HBASE-9328:
--------------------------------------------
Hi [~stack], thanks for looking at it.
Basically, getCompactionStatein HBaseAdmin call the RS using ProtoBuff to get
the compaction state. The RS will return a NotServingRegionException if
required, but it's then encapsulated into a RemoteException. Then the catch
(NotServingRegionException e) will not catch it. It need to be catch into a
catch (RemoteException e). It's what I'm doing here.
If there is any other exception, then it will call throw e; to be consistent
with the current behaviour, and this will be catch on the JSP side which will
do a printStackTrace. So at the end, this will be logged into the .out file
like it was before, but now that will display a nice "unknow" for the state
instead of corrupting the interface.
Before this patch, when an expection occured, UI got corrupted and exception
was logged into the .out file. After this patch, when an exception occurs, the
UI is no more corrupted and it will show "Unknown" for the state. Also if the
server is not serving the region, it will confirm that it's also not compacting.
