Description

HADOOP-1158 (scheduled for 0.15.0) introduced a bug where sometimes the task's diagnostic's messages sent via TaskUmbilicalProtocol.reportDiagnosticInfo are lost. This is due to them being not being saved properly and being overridden in TaskStatus.statusUpdate, simple fix is to append the prev diagnostic message.
