[jira] [Commented] (CASSANDRA-6285) LCS compaction failing with Exception

    [ https://issues.apache.org/jira/browse/CASSANDRA-6285?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13872338#comment-13872338 ] 

Brandon Kearby commented on CASSANDRA-6285:
-------------------------------------------

I'm getting it as well on 2.0.4. I'm testing a new cluster. I don't get the error with one node, but when I add two or more I get the same error.
{code}

Here's the schema I'm testing with:
{code}
create column family signal
  with column_type = 'Standard'
  and comparator = 'UTF8Type'
  and default_validation_class = 'BytesType'
  and key_validation_class = 'UTF8Type'
  and read_repair_chance = 0.1
  and dclocal_read_repair_chance = 0.0
  and gc_grace = 432000
  and min_compaction_threshold = 4
  and max_compaction_threshold = 32
  and replicate_on_write = true
  and compaction_strategy = 'org.apache.cassandra.db.compaction.LeveledCompactionStrategy'
  and caching = 'ALL'
  and compaction_strategy_options = {'sstable_size_in_mb' : '160'}
  and comment = 'A store of information about each individual signal.'
  and column_metadata = [
    {column_name : 'type',
    validation_class : UTF8Type},
    {column_name : 'foo_id',
    validation_class : LongType},
    validation_class : UTF8Type}]
  and compression_options = {'sstable_compression' : 'org.apache.cassandra.io.compress.LZ4Compressor'};
