Subject AW: [MASSMAIL]Cassandra stuck at DataSink running on cluster
Date Fri, 26 Jun 2015 14:06:07 GMT
Hi,

 

I am using Java 7. 

The cassandra version I use is actually 2.1.5, not 1.5. Sorry for the
confusion. 
I also tried cassandra 2.1.6, but the problem stays the same.

 

Best regards,

Susanne

Regards, Susanne.
Which version of Java are you using here?
Have you tested this with more recent versions of Cassandra?

These new version have a lot of improvements related to SSTable reading and
writing, and much more.

I recommend you that you should use at least a 2.1.x version.
Best,

Hi,

 

I am trying to write into Cassandra via the CqlBulkOutputFormat from an
apache flink program. The program succeeds to write into a cassandra-cluster
while the program is running locally on my pc.

However, when trying to run the program on the cluster, it seems to get
stuck at SSTableSimpleUnsortedWriter.put() waiting for the
Diskwriter-Thread, that is not running anymore.

 

I am using cassandra version 1.5 and apache flink version 0.9.0.

 

Attached is the full stacktrace.

 

Thanks in advance,

Susanne
