JiangHua Zhu commented on HDFS-15893:
-------------------------------------
[~Sushma_28], I have noticed this problem, I think it should be judged whether
the value of (dfs.ha.tail-edits.period) is less than or equal to 0, if so, the
default value should be set.
> Logs are flooded when dfs.ha.tail-edits.in-progress set to true or
> dfs.ha.tail-edits.period to 0ms

> When we set dfs.ha.tail-edits.in-progress to true, dfs.ha.tail-edits.period
> to 0ms almost all the logs on standby and observer NN are loaded. Such logs
> will flood useful logs.
> We can adjust the log level of few logs to debug while observer node is in
> operation.
