Subject Re: New nodes won't bootstrap on .66
Date Thu, 28 Oct 2010 15:35:42 GMT
Hi,

I have the same problem with 0.6.5

New nodes will hang forever in bootstrap mode (no streams are being opened)
and the receiver thread just waits for data forever:


 INFO [Thread-53] 2010-10-27 20:33:37,399 SSTableReader.java (line 120)
Sampling index for /hd2/cassandra/data/table_xyz/
table_xyz-3-Data.db
 INFO [Thread-53] 2010-10-27 20:33:37,444 StreamCompletionHandler.java (line
64) Streaming added /hd2/cassandra/data/table_xyz/table_xyz-3-Data.db
