Cassandra sstableloader - Connection refused

Question

I am trying to bulk load a 4 node Cassandra 3.0.10 cluster with some data. I've successfully generated the SStables following the documentation, however it seems like I cannot get the sstableloader load them.

I get the following java.net.ConnectException: Connection refused

bin/sstableloader -v -d localhost test-data/output/si_test/messages/

The utility seems to connect to the cluster ( ...Established connection to initial hosts.. ), however I does not stream the data.

What I've tried so far to debug the issue:

• Dropped the target keyspace (and got a different error), created again via cqlsh

• I can telnet to each node of the cluster through ports 9042 and 7000

• Enabled thrift using nodetool enablethrift

EDIT

That's the output of netstat -an | grep 7000 netstat -an | grep 7000 . The nodes have only one network interface and Cassandra is listening to it. It has also established connections with all the other nodes on port 7000.

EDIT 2

Changing the initial host from 127.0.0.1 to the actual address of the node in the network results to a com.datastax.driver.core.exceptions.TransportException :

Any suggestion is appreciated.

Answer 1

Thats it trying to connect to the storage port (7000). Its most likely binding to a different interface than 127.0.0.1 . You can check what its binding too with netstat -an | grep 7000 netstat -an | grep 7000 . You may want to double check any firewall or iptable settings.

UPDATE: its not bound to 127.0.0.1 which is default but to 172.31.3.88. So call sstableloader -v -d 172.31.3.88 test-data/output/si_test/messages/

Also if you have ssl enabled ( server_encryption_options in cassandra.yaml) you need to use 7001 and configure it to match. If you can telnet to 7000 its most likely not that though.

Worth noting that enabling thrift is not necessarily in 3.0.10. sstableloader no longer uses that (in older versions it was used to read the schema).

解决了将cassandra.yaml文件中的rpc_address从默认本地主机更改为每个节点的实际地址的问题。
