Subject [jira] [Commented] (CASSANDRA-6965) sstableloader fails to stream data
Date Wed, 02 Apr 2014 00:59:19 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-6965?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13957207#comment-13957207
] 

Yuki Morishita commented on CASSANDRA-6965:
-------------------------------------------

It looks like this is regression from CASSANDRA-6596.

Root stack trace is:
{code}
Exception in thread "STREAM-OUT-/127.0.0.1" java.lang.NullPointerException
        at org.apache.cassandra.streaming.StreamManager$StreamRateLimiter.<init>(StreamManager.java:79)
        at org.apache.cassandra.streaming.StreamManager.getRateLimiter(StreamManager.java:61)
        at org.apache.cassandra.streaming.StreamWriter.<init>(StreamWriter.java:60)
        at org.apache.cassandra.streaming.compress.CompressedStreamWriter.<init>(CompressedStreamWriter.java:47)
        at org.apache.cassandra.streaming.messages.OutgoingFileMessage$1.serialize(OutgoingFileMessage.java:51)
        at org.apache.cassandra.streaming.messages.OutgoingFileMessage$1.serialize(OutgoingFileMessage.java:40)
        at org.apache.cassandra.streaming.messages.StreamMessage.serialize(StreamMessage.java:45)
        at org.apache.cassandra.streaming.ConnectionHandler$OutgoingMessageHandler.sendMessage(ConnectionHandler.java:389)
        at org.apache.cassandra.streaming.ConnectionHandler$OutgoingMessageHandler.run(ConnectionHandler.java:359)
        at java.lang.Thread.run(Thread.java:744)
{code}

Line 79 of StreamManager.java indicates that DC names should be loaded from cassandra.yaml
file, but in sstableloader cassandra.yaml should not be readed.
[~vijay2win@yahoo.com] can you take a look?
