This means that your tablet server is currently running while you tried to do 
the repair. Please stop the service first.

Hi, Todd
   Sorry, the problem is not described clearly??I use the following command:  
kudu fs check -fs_wal_dir=/app/kudu/tserver/ -fs_data_dirs=/app/kudu/tserver 
-repair=true
I can execute the above command, prompting the following log information:

 Hi, guys!
     I executed the kudu fs check command encountered an error:
Command: kudu fs check -fs_wal_dir = /app/kudu/tserver/ -fs_data_dirs = 
/app/kudu/tserver -repair = true




Is this the exact command you executed? You should not have any space 
characters between the flag and its argument. eg instead use:


kudu fs check --fs_wal_dir=/app/kudu/tserver --repair


If you can paste the exact output as well, that would be helpful. I don't see 
any error message below, just "INFO" level status messages.
 
Error log:

Password error / app / kudu / tserver / data / block_man
What do I need to pay attention to when I use this command? Need to stop kudu 
cluster?
I use the kudu version: kudu 1.4.0-cdh5.12.0
 


 with best regards, lizhong
