Jouni Hartikainen updated CASSANDRA-5097:
-----------------------------------------
Affects Version/s: 1.2.0
> cassandra-shuffle fails as system keyspace is not user-modifiable
> -----------------------------------------------------------------
>
> Key: CASSANDRA-5097
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5097
> Project: Cassandra
> Issue Type: Bug
> Affects Versions: 1.2.0 rc2, 1.2.0
> Reporter: Jouni Hartikainen
>
> cassandra-shuffle tool fails to insert calculated relocations into the system
> keyspace as it is not user-modifiable. When run, the following exception is
> thrown after printing out the list of relocations for the first node in ring:
> Exception in thread "main" java.lang.RuntimeException:
> InvalidRequestException(why:system keyspace is not user-modifiable.)
> at
> org.apache.cassandra.tools.Shuffle.executeCqlQuery(Shuffle.java:516)
> at org.apache.cassandra.tools.Shuffle.shuffle(Shuffle.java:359)
> at org.apache.cassandra.tools.Shuffle.main(Shuffle.java:678)
> Caused by: InvalidRequestException(why:system keyspace is not
> user-modifiable.)

> By quickly checking the code it seems that the patch set for CASSANDRA-4874
> disallows modifications to system keyspace again (they were previously
> allowed by CASSANDRA-4664) thus rendering cassandra-shuffle unable to do its
> job.
