Description

Just saw the following NPE on trunk. Means, that metaData from CFMetaData metaData = compaction.getCompactionInfo().getCFMetaData(); is null. A simple if (metaData == null) continue; should fix this.

Caused by: java.lang.NullPointerException: null
	at org.apache.cassandra.metrics.CompactionMetrics$2.getValue(CompactionMetrics.java:103) ~[main/:na]
	at org.apache.cassandra.metrics.CompactionMetrics$2.getValue(CompactionMetrics.java:78) ~[main/:na]
