It is often useful to enable them for troubleshooting but the verbosity of the logs slows down the NameNode. > It would be good to have an option to send BlockStateChange logs to an alternate async appender to limit the performance impact. There would be no change to the default behavior. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
