3. Exception handling
In Fayson's eyes, seeing ERROR-level logs is annoying, even if there are no exceptions that affect it. Here Fayson tells you how to block such ERROR logs.
1. Log in to CM to enter the configuration page of the Hive service and select "HiveServer2" in the category.
two。 Search the search bar for "HiveServer2 logging advanced configuration code snippet (safety valve)" and add the following configuration:
Log4j.appender.RFA.filter.1=org.apache.log4j.filter.ExpressionFilter
Log4j.appender.RFA.filter.1.Expression=EXCEPTION ~ = org.apache.thrift.transport.TSaslTransportException
Log4j.appender.RFA.filter.1.AcceptOnMatch=false

3. Just restart the HiveServer2 service after saving the configuration
