> {quote}
> The function "remove" does NOT remove the block from all queues.
> Function add from LowRedundancyBlocks.java is used on some places and maybe 
> one block in two or more queues.
> We found that corrupt blocks mismatch corrupt files on NN web UI. Maybe it is 
> related to this.
> Upload initial patch
