I suddenly started getting this error using the code that was perfectly working a day before. The library containing yammer metrics exists and part of mvn build. Please help how to resolve the issue or disable yammer.metrics.
Thanks in advance Exception in thread "Thread-3" java.lang.NoClassDefFoundError: Could not initialize class com.yammer.metrics.Metrics at kafka.metrics.KafkaMetricsGroup$class.newTimer(KafkaMetricsGroup.scala:52) at kafka.consumer.FetchRequestAndResponseMetrics.newTimer(FetchRequestAndResponseStats.scala:25) at kafka.consumer.FetchRequestAndResponseMetrics.<init>(FetchRequestAndResponseStats.scala:26) at kafka.consumer.FetchRequestAndResponseStats.<init>(FetchRequestAndResponseStats.scala:37) at kafka.consumer.FetchRequestAndResponseStatsRegistry$$anonfun$2.apply(FetchRequestAndResponseStats.scala:50) at kafka.consumer.FetchRequestAndResponseStatsRegistry$$anonfun$2.apply(FetchRequestAndResponseStats.scala:50) at kafka.utils.Pool.getAndMaybePut(Pool.scala:61) at kafka.consumer.FetchRequestAndResponseStatsRegistry$.getFetchRequestAndResponseStats(FetchRequestAndResponseStats.scala:54) at kafka.consumer.SimpleConsumer.<init>(SimpleConsumer.scala:39) at kafka.javaapi.consumer.SimpleConsumer.<init>(SimpleConsumer.scala:34) at com.tagged.etlhub.client.kafka.connector.driver.LeaderDiscovery.connectToLeader(LeaderDiscovery.java:90) at com.tagged.etlhub.client.kafka.connector.driver.LeaderDiscovery.findLeader(LeaderDiscovery.java:50) at com.tagged.etlhub.client.kafka.connector.driver.Connector.connect(Connector.java:208) at com.tagged.etlhub.client.kafka.connector.driver.Connector.createConnector(Connector.java:65) at com.tagged.etlhub.client.kafka.connector.driver.ConnectorFactory.getConnector(ConnectorFactory.java:11) at com.tagged.etlhub.client.kafka.message.TopicMessages.getConnector(TopicMessages.java:156) at com.tagged.etlhub.client.kafka.message.TopicMessages.connect(TopicMessages.java:45) at com.tagged.etlhub.client.StreamThreadPool.startStream(StreamThreadPool.java:109) at com.tagged.etlhub.client.StreamThreadPool.access$0(StreamThreadPool.java:93) at com.tagged.etlhub.client.StreamThreadPool$1.run(StreamThreadPool.java:73) at java.lang.Thread.run(Unknown Source)
