--------------------------------------------------------------------
Problem appears after ugprading 1.0.6 to 1.0.7. I've create only one keyspace
with 4 column family. All of my CF are:
with column_type = 'Standard'
and comparator = 'AsciiType'
and default_validation_class = 'AsciiType'
and key_validation_class = 'AsciiType'
and rows_cached = 0.0
and row_cache_save_period = 0
and row_cache_keys_to_save = 2147483647
and keys_cached = 200000.0
and key_cache_save_period = 14400
and read_repair_chance = 1.0
and gc_grace = 864000
and min_compaction_threshold = 2
and max_compaction_threshold = 4
and replicate_on_write = true
and row_cache_provider = 'ConcurrentLinkedHashCacheProvider'
and compaction_strategy =
'org.apache.cassandra.db.compaction.LeveledCompactionStrategy'
and compaction_strategy_options = {'sstable_size_in_mb' : '4096'}
and compression_options = {'chunk_length_kb' : '64', 'sstable_compression' :
'org.apache.cassandra.io.compress.SnappyCompressor'};
system keyspace is untouched, I didn't change it.
After upgrading node try to use 'nodetool -h $IP compactionstats'
And that's all.
