The file does not appear on disk and the permissions are definitely correct.  
We have seen the file in snapshots.   This is completely blocking us from 
adding the new node.  How can we recover?  Just run repairs?

Thanks

This is somewhat serous, specially if it's from the a bug in dropping tables. 
Though I would expect that would show up for a lot of people.

Does the file exist on disk?
Are the permissions correct ?

IMHO you need to address this issue on the existing nodes before worrying about 
the new node.

Let me know if this fixes the problem?

So the problem is that when you dropped and recreated the table with the same 
name, some how the old CFStore object was not purged. So now there were two 
objects which caused same sstable to have 2 SSTableReader object.

The fix is to find all nodes which is emitting this FileNotFound Exception and 
restart them.

In your case, restart the node which is serving the data and emitting 
FileNotFound exception.

Once this is up, again restart the bootstrapping node with bootstrap argument. 
Now it will successfully stream the data.

Yes we likely dropped and recreated tables.  If we stop the sending node, what 
will happen to the bootstrapping node?

Hi,
    The problem is that the node sending the stream is hitting this 
FileNotFound exception. You need to restart this node and it should fix the 
problem.

Are you seeing lot of FileNotFoundExceptions? Did you do any schema change 
recently?

Hi all,

   I have been trying to bootstrap a new node into my 7 node 1.2.4 C* cluster 
with Vnodes RF3 with no luck.  It gets close to completing and then the 
streaming just stalls with  streaming at 99% from 1 or 2 nodes.  Nodetool 
netstats shows the items that have yet to stream but the logs on the new node 
do not show any errors.  I tried shutting down then node, clearing all 
data/commit logs/caches, and re-boot strapping with no luck.  The nodes that 
are hanging sending the data only have the error below but that's related to 
compactions (see below) although it is one of the files that is waiting to be 
sent.  I tried nodetool scrub on the column family with the missing item but 
got an error indicating it could not get a hard link.  Any ideas?  We were able 
to bootstrap one of the new nodes with no issues but this other one has been a 
real pain.  Note that when the new node is joining the cluster, it does not 
appear in nodetool status.  Is that expected?

Thanks all, my next step is to try getting a new IP for this machine, my 
thought being that the cluster doesn't like me continuing to attempt to 
bootstrap the node repeatedly each time getting a new host id.
