hemanthboyina commented on HDFS-15246:
--------------------------------------
the scenario here is ,
created a file "file1" in a directory "dir1" and created snapshot of the dir1 ,
moved the file1 inside the dir1 to "/" (rootDir)
Now on doing truncate to the "/file1" , it is modifying the content of file
which exists the snapshot too
so on getting the file1 which exists in snapshot i am getting
ArrayIndexofBoundsException , as the file size i.e blocksize got modified
becuase of truncate , but the filediff didnt modified
any suggestions for this ?
