--------------------------------------
{quote}One item to consider is that you may be duplicating what
getServerNameFromWALDirectoryName#getServerNameFromWALDirectoryName does? Is
that possible?
{quote}
Sorry, I don't get this. The method getServerNameFromWALDirectoryName is used
to extract serverName from WAL Directory. The serverName I got is from user's
input. Seems not related?
{quote}If making a new patch, you might check if the Procedure is finished
before claiming one is running (it may not be running):
if (serverName.compareTo(((ServerCrashProcedure) procedure).getServerName()) ==
0) {
{quote}
Sure. I'll check if the procedure is still running.

> According to my test, if one RS is down, then all procedure logs are deleted,
> it will lead to that no ServerCrashProcedure is scheduled. And restarting
> master cannot help. Thus we need to schedule a ServerCrashProcedure manually
> to solve the problem. I plan to add a scheduleServerCrashProcedure() API to
> HbckService, then add this API to HBCK2.
