-----------------------------------------------------------
[~StephanEwen] I figured out that it is because since 3.5.3 ZooKeeper default
disable four letter words which HBase uses for waiting for server up. We can
set the property in Flink test scope to enable four letter words and workaround
this issue. Have patched the fix in private branch and still digging whether
there are other issues.
