Subject Exception at Tried to hard link to file that does not exist
Date Wed, 15 Oct 2014 01:37:29 GMT
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 /var/cassandra/data/forseti/activity/forseti-activity-jb-3-CompressionInfo.db at

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!
