Jordan West created CASSANDRA-17254:
---------------------------------------
Summary: nodetool toppartitions can fail because
ByteBuffer.array() returns more bytes than would be considered valid by
UTF8Serializer.validate
Key: CASSANDRA-17254
URL: https://issues.apache.org/jira/browse/CASSANDRA-17254
Project: Cassandra
Issue Type: Bug
Reporter: Jordan West
Assignee: Jordan West
The error below is caused by the use of
[{{ByteBuffer.array()}}|https://github.com/apache/cassandra/blob/cassandra-3.0/src/java/org/apache/cassandra/db/ColumnFamilyStore.java#L1628].
Doing so not only makes the hex key potentially incorrect but causes invalid
data to be passed to {{AbstractType.getString}} and ultimately
{{UTF8Validator.validate}}.
{code}
error: String didn't validate.
-- StackTrace --
org.apache.cassandra.serializers.MarshalException: String didn't validate.
