Hi,
I'm new to cassandra and told to write a script to backup the cassandra cluster
every day, but it throws an exception at one node as below:
Exception in thread "main" java.lang.RuntimeException: Tried to hard link to
file that does not exist

noted I have three nodes, this occurs at one node, someone knows how to solve
this problem?
I got a method that restart the one node occurs error, does it safely?
Thanks all!
