I have started hadoop cluster with one NameNode And one DataNode and written one file with replication factor one.
Now Edited((To get check-sum error)) written file in DN where block is located(physically).
Then I tried to read file ,then I got could not obtain block since block got corrupted and check-sum error from DN logs.
After that I removed what ever I edited from block .
Then I try to read file,here I am able to read by using fsshell commands even though block got corrupted(by fsck report)..But I am getting eof execption using readfully api.
After reverting not getting any checksum error from DN logs.
Please let me know the behavior once revert back to original
Thanks And Regards
