What is the Reason for a corrupt block

Hello Guys,

i have few questions regadring corrupt block ,it would be really great if someone can help me on it.


1)Can anyone let me know what is the specific reason for a corrupt block.

2)If i have a replication factor as 3 , then why do i receive corrupt block alert , doesnt the name node repair the corrupt block by copying a good block from another node?

3)is it okay to  remove that particular block/file when i receive this alert ? will the name node then scan and find 2 replicas instead of 3 and copy 1 replica to the node to make it as  3 in order to maintain the replication factor as 3.


Thank you.
