> Key: BEAM-3425
> URL: https://issues.apache.org/jira/browse/BEAM-3425
> Project: Beam
> Issue Type: Bug
> Components: io-java-cassandra

> See exception in
> https://stackoverflow.com/questions/48090668/how-to-increase-dataflow-read-parallelism-from-cassandra/48131264#48131264
> .
> The exception comes from
> https://github.com/apache/beam/blob/master/sdks/java/io/cassandra/src/main/java/org/apache/beam/sdk/io/cassandra/CassandraServiceImpl.java#L279
> , where I suppose "range_start" and "range_end" are really varchar, but the
> code expects them to be long.
> Indeed they are varchar:
> https://github.com/apache/cassandra/blob/4c80eeece37d79f434078224a0504400ae10a20d/src/java/org/apache/cassandra/db/SystemKeyspace.java#L238
> and have been for at least the past 3 years.
> However really they seem to be storing longs:
> https://github.com/apache/cassandra/blob/95b43b195e4074533100f863344c182a118a8b6c/src/java/org/apache/cassandra/hadoop/cql3/CqlInputFormat.java#L229
> So I guess all that needs to be fixed is adding a Long.parseLong.
