[jira] [Commented] (CASSANDRA-4206) AssertionError: originally
calculated column size of 629444349 but now it is 588008950
[ https://issues.apache.org/jira/browse/CASSANDRA-4206?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13675709#comment-13675709 ]
Alain RODRIGUEZ commented on CASSANDRA-4206:
--------------------------------------------
Similar thing over here.
C*1.2.2
I have a lot of hints (3 & 4 GB) on 2 nodes out of 12 due to an unknown issue while growing to multiple datacenter (all the nodes of the new datacenter saw themselves as UNREACHABLE from the cassandra-cli - nodetool ring is ok...).
On these 2 nodes I see now :

> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.0.9
> Environment: Debian Squeeze Linux, kernel 2.6.32, sun-java6-bin 6.26-0squeeze1
> Reporter: Patrik Modesto
>
> I've 4 node cluster of Cassandra 1.0.9. There is a rfTest3 keyspace with RF=3 and one CF with two secondary indexes. I'm importing data into this CF using Hadoop Mapreduce job, each row has less than 10 colkumns. From JMX:
> MaxRowSize: 1597
> MeanRowSize: 369
> And there are some tens of millions of rows.
> It's write-heavy usage and there is a big pressure on each node, there are quite some dropped mutations on each node. After ~12 hours of inserting I see these assertion exceptiona on 3 out of four nodes:

> I think the problem may be somehow connected to an IntegerType secondary index. I had a different problem with CF with two secondary indexes, the first UTF8Type, the second IntegerType. After a few hours of inserting data in the afternoon and midnight repair+compact, the next day I couldn't find any row using the IntegerType secondary index. The output was like this:
> {noformat}
> [default@rfTest3] get IndexTest where col1 = '3230727:http://zaskolak.cz/download.php';
> -------------------
> RowKey: 3230727:8383582:http://zaskolak.cz/download.php

> [default@rfTest3] get IndexTest where col2 = 8383583;
> 0 Row Returned.
> Elapsed time: 7 msec(s
> {noformat}
> You can see there really is an 8383583 in col2 in on of the listed rows, but the search by secondary index returns nothing.
> The Assert Exception also happend only on CF with the secondary index of IntegerType. There were also secondary indexes of UTF8Type and
> LongType types. It's the first time I've tried secondary indexes of other type than UTF8Type.
