HDFS missing blocks reported even if there is no missing/corrupt blocks

[#1]

Hi

Guys why after running :

hdfs fsck / -delete 

I am seeing this info when connecting to active NN

If I failover to the Standby node this message will disappear, but if the corruption will happen again i will have same thing.

Is there way to fix the issue ?

Thanks

I can't find the hint from the code that you wrote to show to the student like me over here. I have highlighted the errors, please check and correct it.janitorial services

@David Nicholas i am not sure i understand what you are trying to say ?

can you explain please. Above problem is that after running fsck and clearing missing blocks i still see the info about missing blocks without of any references to the blocks

when connecting to http://active_nn::50070/dfshealth.html#tab-overview

so my question is why i am seeing this ?
