HeartSaVioR edited a comment on issue #23776: [SPARK-26650][core] Demote noisy 
HBase-related log message.
URL: https://github.com/apache/spark/pull/23776#issuecomment-463425208
 
 
   Yeah and previously I had to request customer to turn on debug log and rerun 
query to get such information (failed to track down the issue so requested to 
turn on debug log level and found the reason), hence I proposed to make the log 
level be consistent. Please see #23418. 
   
   This patch suggests to roll back the change: when we want to roll back the 
log level, adding comment like `it is intentionally set to debug to avoid being 
noisy for non-HBase related query` would help avoiding to fix level back and 
forth.
   
   > Putting this in a separate module is not just something that should be as 
separate change, but also means we'd have an opinion about what version of 
HBase Spark is built against.
   
   Please correct me if I'm missing here: if my understanding is right, once 
current approach doesn't deal with HBase version, putting this in a separate 
module also doesn't need to deal with HBase version (we will still rely on 
reflection even in that case). End users just need to dynamically link the new 
package if they use HBase with Kerberos enabled.
