Zhuoyue Huang commented on HBASE-25549:
---------------------------------------
{quote}Can this be a modifier of the existing alter command instead?{quote}
{quote}So perhaps better to make it a part of the actual alter command itself
and let the users force it (if needed) with a warning on the console?{quote}

Thanks for your suggestions. I Will try to add an optional flag for command
alter. Users can trigger it as they want
> A new hbase shell command: 'alter_lazy'

> Under normal circumstances, modifying a table will cause all regions
> belonging to the table to enter RIT. Imagine the following two scenarios：
> # Someone entered the wrong configuration （e.g. negative
> 'hbase.busy.wait.multiplier.max' value） when altering the table, causing
> thousands of online regions to fail to open, leading to online accidents.
> # Modify the configuration of a table, but this modification is not urgent,
> the regions are not expected to enter RIT immediately.
> 'alter_lazy' is a new command to modify a table without reopening any online
> regions except those regions were assigned by other threads or split etc.
