[jira] [Commented] (CASSANDRA-5202) AssertionError in the backend:
"DecoratedKey(-1, ) != DecoratedKey(x, y) ..." while querying data after
bulk insert - 1M rows with 100 columns. Also failure to drop column
families
[ https://issues.apache.org/jira/browse/CASSANDRA-5202?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13566672#comment-13566672 ]
Marat Bedretdinov commented on CASSANDRA-5202:
----------------------------------------------
The sever is a single node Cassandra 1.1.9 release drop and there is one and only client running at the same time.

> Key: CASSANDRA-5202
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5202
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.1.9
> Environment: OS: Windows 7,
> Server: Cassandra 1.1.9 release drop
> Client: astyanax 1.56.21,
> JVM: Sun/Oracle JVM 64 bit (jdk1.6.0_27)
> Reporter: Marat Bedretdinov
> Labels: test
> Attachments: astyanax-stress-driver.zip

> Attached is a driver that sequentially:
> 1. Drops keyspace
> 2. Creates keyspace
> 4. Creates 2 column families
> 5. Seeds 1M rows with 100 columns
> 6. Queries these 2 column families
> The above steps are repeated 1000 times.
> The following exception is observed at random (race - SEDA?):

> This exception appears in the server at the time of client submitting a query request (row slice) and not at the time data is seeded. The client times out and this data can no longer be queried as the same exception would always occur from there on.
> Also on iteration 201, it appears that dropping column families failed and as a result their recreation failed with unique column family name violation (see exception below). Note that the data files are actually gone, so it appears that the server runtime responsible for creating column family was out of sync with the piece that dropped them:
