Hi all,

 

I ran decommission on a node in my 32 node cluster. After about an hour of streaming files to another node, I got this error on the node being decommissioned:

And this message on the node that it was streaming to:

INFO [Thread-333] 2011-05-03 21:49:00,234 StreamInSession.java (line 121) Streaming of file /raiddrive/MDR/MeterRecords-f-2283-Data.db/(98605680685,197932763967)

         progress=49016107008/99327083282 - 49% from org.apache.cassandra.streaming.StreamInSession@33721219 failed: requesting a retry.

 

I tried running decommission again (and running scrub + decommission), but I keep getting this error on the same file.

 

I checked out the file and saw that it is a lot bigger than all the other sstables… 184GB instead of about 74MB. I haven’t run a major compaction for a bit, so I’m trying to stream 658 sstables.

 

I’m using Cassandra 0.7.4, I have two data directories (I know that’s not good practice…), and all my nodes are on Amazon EC2.

 

Any thoughts on what could be going on or how to prevent this?

 

Thanks!

Tamara
