Jordan West commented on CASSANDRA-17254:
-----------------------------------------
If I am reading the 3.11 code right (pasted below jic), it uses {{bytesToHex}}
for the key but just uses the {{ByteBuffer}} directly unlike my patch which
duplicates it. I am fine with the 3.11 approach as well assuming the comment is
correct:
{code:java}
//Not duplicating the buffer for safety because AbstractSerializer and
ByteBufferUtil.bytesToHex
//don't modify position or limit
ByteBuffer key = counter.getItem();
result.put(new CompositeDataSupport(COUNTER_COMPOSITE_TYPE, COUNTER_NAMES, new
Object[] {
ByteBufferUtil.bytesToHex(key), // raw
counter.getCount(), // count
counter.getError(), // error
metadata.getKeyValidator().getString(key) })); // string {code}
> nodetool toppartitions can fail because ByteBuffer.array() returns more bytes
> than would be considered valid by UTF8Serializer.validate

> URL: https://issues.apache.org/jira/browse/CASSANDRA-17254
> Project: Cassandra
> Issue Type: Bug
> Components: Tool/nodetool
> Reporter: Jordan West
> Assignee: Jordan West
> Priority: Normal
> Fix For: 3.0.x, 3.11.x
>
>
> 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.
