> Nodetool compactionstats fails with NullPointerException
> --------------------------------------------------------
>
> Key: CASSANDRA-4318
> URL: https://issues.apache.org/jira/browse/CASSANDRA-4318
> Project: Cassandra
> Issue Type: Bug
> Affects Versions: 1.1.1
> Environment: 2 node cluster running on Ubuntu 10.10 64-bit
> 16GB Max Heap allocated to each node.
> Test keyspace using replication factor 2
> Reporter: David B
> Assignee: Jonathan Ellis
> Priority: Minor
> Labels: caching
> Fix For: 1.1.2
>
> Attachments: 4318.txt
>
>
> Test uses Column family C defined as follows:
> create column family C with caching = 'keys_only' and key_validation_class = 'LongType' and compression_options = { sstable_compression: SnappyCompressor, chunk_length_kb: 64 } and max_compaction_threshold=0;
> max_compaction_threshold is set to 0 to disable auto compaction.
> SSTables are streamed via sstableloader, after which a major compaction is triggered using "nodetool compact MyKeyspace C".
> Thereafter, attempts to request compaction stats via "nodetool compactionstats" fail with the following exception:
> Exception in thread "main" java.lang.NullPointerException
