[jira] [Commented] (CASSANDRA-9381) AbstractColumnFamilyInputFormat
is incorrectly interpreting token values when building ColumnFamilySplit
[ https://issues.apache.org/jira/browse/CASSANDRA-9381?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14543624#comment-14543624 ]

Is this a new regression?
> AbstractColumnFamilyInputFormat is incorrectly interpreting token values when building ColumnFamilySplit
> --------------------------------------------------------------------------------------------------------
>
> Key: CASSANDRA-9381
> URL: https://issues.apache.org/jira/browse/CASSANDRA-9381
> Project: Cassandra
> Issue Type: Bug
> Components: Hadoop
> Reporter: Mike Adamson
> Fix For: 2.2.x
>
>
> The SplitCallable.call method in AbstractColumnFamilyInputFormat has the following code for building ColumnFamilySplits:
> {noformat}
> for (TokenRange subSplit : subSplits.keySet())
> {
> List<TokenRange> ranges = subSplit.unwrap();
> for (TokenRange subrange : ranges)
> {
> ColumnFamilySplit split =
> new ColumnFamilySplit(
> subrange.getStart().toString().substring(2),
> subrange.getEnd().toString().substring(2),
> subSplits.get(subSplit),
> endpoints);
> logger.debug("adding {}", split);
> splits.add(split);
> }
> }
> {noformat}
> The subrange.getStart().toString().substring(2) works for the OrderPreservingPartitioner because the toString for the OPPToken in the java driver returns a hex value preceded by 0x. It doesn't work for the Murmur3Partitioner because the toString for the M3PToken returns Long.toString.
> As a result the tokens lose their first 2 digits.
