Description

Upgradesstables in C* 2.1 fails on thrift tables originally created on C*1.2 with the following error:

$ nodetool upgradesstables -a
error: org.apache.cassandra.db.composites.CompoundComposite cannot be cast to org.apache.cassandra.db.composites.CellName

This problem is not seen if the thrift table was originally created in C* 2.0.x

The suspicion is that this is related to the use of a CompositeType comparator.

The following schema is an example of a cf that will cause this issue.

create column family cf1
  with column_type = 'Standard'
  and comparator = 'CompositeType(org.apache.cassandra.db.marshal.ReversedType(org.apache.cassandra.db.marshal.DateType),org.apache.cassandra.db.marshal.UUIDType,org.apache.cassandra.db.marshal.AsciiType,org.apache.cassandra.db.marshal.UUIDType,org.apache.cassandra.db.marshal.UUIDType,org.apache.cassandra.db.marshal.AsciiType,org.apache.cassandra.db.marshal.AsciiType,org.apache.cassandra.db.marshal.AsciiType,org.apache.cassandra.db.marshal.AsciiType,org.apache.cassandra.db.marshal.AsciiType,org.apache.cassandra.db.marshal.AsciiType)'
  and default_validation_class = 'UTF8Type'
  and key_validation_class = 'CompositeType(org.apache.cassandra.db.marshal.LongType,org.apache.cassandra.db.marshal.IntegerType)'
  and read_repair_chance = 1.0
  and dclocal_read_repair_chance = 0.0
  and populate_io_cache_on_flush = false
  and gc_grace = 259200
  and min_compaction_threshold = 4
  and max_compaction_threshold = 32
  and replicate_on_write = true
  and compaction_strategy = 'org.apache.cassandra.db.compaction.SizeTieredCompactionStrategy'
  and caching = 'KEYS_ONLY'
  and compression_options = {'sstable_compression' : 'org.apache.cassandra.io.compress.SnappyCompressor', 'chunk_length_kb' : '64'};

You can workaround this via the creation of a dummy table and update of schema_columnfamilies for each cf affected. The dummy cf can be deleted afterwards.

cassandra-cli

[default@unknown] use ks1;
[default@ks1] create column family foo;
[default@ks1] use system;
[default@system] set schema_columnfamilies['ks1']['cf1:is_dense']=01;
[default@system] use ks1;
[default@ks1] update column family foo with comment='';
