Hello everyone,<br><br> I have a 2 DC (DC1:3 and DC2:6) Cassandra1.0.7 setup. I have about 300GB/node in the DC2. <br><br> The DCs are communicating over a gateway where I do NAT for ports 7000, 9160 and 7199.<br><br> I did a &quot;nodetool repair&quot; on a node in DC2 without any external load on the system. <br>
<br> It took 5 hrs to finish the Merkle tree calculations (which is fine for me) but then in the streaming phase nothing happens (0% seen in &quot;nodetool netstats&quot;) and stays like that forever. Note: it has to stream to/from nodes in DC1!<br>
<br> I tried another time and still the same.<br><br> Looking around I found this thread  <br>             <a href="http://www.mail-archive.com/user@cassandra.apache.org/msg22167.html">http://www.mail-archive.com/user@cassandra.apache.org/msg22167.html</a><br>
 which seems to describe the same problem.<br><br>The thread gives 2 suggestions:<br>- a full cluster restart allows the first attempted repair to complete (haven&#39;t tested yet; this is not practical even if it works)<br>
- issue <a href="https://issues.apache.org/jira/browse/CASSANDRA-4223">https://issues.apache.org/jira/browse/CASSANDRA-4223</a> can be the problem <br><br>Questions:<br>1) How can I make sure that the JIRA issue above is my real problem? (I see no errors or warns in the logs; no other activity)<br>
2) What should I do to make the repairs work? (If the JIRA issue is the problem, then I see there is a fix for it in Version 1.0.11 which is not released yet)<br><br>Thanks,<br>Alex<br>
