DadanielZ commented on issue #1621: HADOOP-16640. WASB: Override 
getCanonicalServiceName() to return URI
URL: https://github.com/apache/hadoop/pull/1621#issuecomment-540838767
 
 
   @steveloughran Here is the issue reported by wasb customer:
   HBase calls getCanonicalServiceName() to check if two FS are the same, but 
because the current WASB rely on the default implementation of 
getCanonicalServiceName() so it will return "ip:port", which failed to catch 
the case that two accounts are on same stamp.
   
https://github.com/apache/hbase/blob/10180e232ebf886c9577d77eb91ce64b51564dfc/hbase-server/src/main/java/org/apache/hadoop/hbase/util/FSHDFSUtils.java#L117
   So we would like to add one config to bypass this issue.
   
   BTW, from the documentation, this API should only be used by token cache but 
not others, so it seem HBase should not rely on this call to do the check?
