+  <description>
+        If this property is enabled, the datanode will instruct the
+        operating system to sync data block files contents to disk when the
+        blockfile is closed. This can help data loss in the event of a malfunction such as a power
+        failure.
+
+        This has the benefit of ensuring that data is written to disk
+        immediately when a block is closed, avoiding the data being held
+        solely in the operating system cache. This can help data loss in the event
+        of a malfunction such as a power failure.
