I also provided a patch a few days ago (see attached file cassandra-2.1-9071.txt, maybe I should have added a comment to make it more explicit :) ) This is a similar approach, but mine only keep the DecoratedKey (there is no need to keep the whole previous CF, and can consume more memory if the CF has many columns) Concerning the unit test, it needs to at least write first a full buffer then write the second one (the first buffer never has an empty partition). Moreover, to increase chances of triggering this false assertion, it’s better to have the decorated key bigger than the value (and only have one column per CF). (This increases the fact that, when “sync” is called, no more columns are written in the empty CF) Don’t hesitate to have a look at the unit test I submitted in the patch (I tested it without (test failed) and with my patch (test passed) ) CQLSSTableWriter gives java.lang.AssertionError: Empty partition Key: CASSANDRA-9071 URL: https://issues.apache.org/jira/browse/CASSANDRA-9071 Project: Cassandra Issue Type: Bug Components: Tools Environment: java 7 / 8 cassandra 2.1.3 snapshot build locally with last commit https://github.com/apache/cassandra/commit/6ee4b0989d9a3ae3e704918622024fa57fdf63e7 macos Yosemite 10.10.2 Reporter: Ajit Joglekar Assignee: Fabien Rousseau Fix For: 2.1.x Attachments: EmailWriter.java, Screen Shot 2015-04-15 at 11.14.40 PM.png, cassandra-2.1-9071.txt, data.csv.gz I am always getting the following error: Exception in thread main java.lang.AssertionError: Empty partition at org.apache.cassandra.io.sstable.SSTableSimpleUnsortedWriter$DiskWriter.run(SSTableSimpleUnsortedWriter.java:228) It happens at a certain point that seems to be repeatable.

The more piercing criticism of my patch is that I addressed the opposite end of the situation (even missing the obvious intent from the prior naming of the variables). In fact while it looked to me like the last record written to could be empty, we only ever flush after at least one cell is present, so that isn't a risk. Thanks for pointing out your patch.

-
I hava the same problem with cassandra 2.1.4. When I was loading large dataset
into C* with SSTableSimpleUnsortedWriter,
I got an *java.lang.AssertionError: Empty partition*
{code:title=test.java|borderStyle=solid}
System.setProperty(cassandra.config,file:///Users/zn/workspace/sstable-csv-m/conf/cassandra.yaml);
String keyspace = app;
File directory = new File(app/sstables/);
if (!directory.exists()){
directory.mkdir();
}
Murmur3Partitioner partitioner = new Murmur3Partitioner();
SSTableSimpleUnsortedWriter usersWriter = new
SSTableSimpleUnsortedWriter(
directory,partitioner,keyspace,Users,AsciiType.instance,null,32);
long timestamp = System.currentTimeMillis() * 1000;
StringBuilder s = new StringBuilder(test);
for (int x=0;x6;x++){
s.append(aa);
}
String x = s.toString();
for(int i=0; i 100; i++)
{
ByteBuffer uuid = ByteBuffer.wrap(decompose(UUID.randomUUID()));
usersWriter.newRow(uuid);
usersWriter.addColumn(bytes(id), bytes(i), timestamp);
usersWriter.addColumn(bytes(lastname), bytes(x), timestamp);
if ((i % 1000) == 0){
System.out.println((i/1000) + + K records wrote);
}
}
usersWriter.close();
System.exit(0);
{code}
After some debuging work, I found, the buffer which was pushed in *writeQueue*
had some empty *ColumnFamily*, which casued the exception.

converting 400 million records into multiple SSTables and creating small test
is a challenge
Last comment from Benedict looks relevant here
