   config property `requestedSecretLifetime`. This helps reducing frequent Pod restarts ([#619]).
 - Run a `containerdebug` process in the background of each HDFS container to collect debugging information ([#629]).
 
+### Changed
+
+- Switch the WebUI liveness probe from `httpGet` to checking the tcp socket.

 ### Fixed
 
 - BREAKING: Use distinct ServiceAccounts for the Stacklets, so that multiple Stacklets can be
