Hi, I have a Kafka cluster running, and periodically, the active controller fails. This causes issues with the Splunk sink connector and therefore stops the process of streaming audit data from Cloudera to Splunk. The error I'm getting over and over is: [2019-02-21 14:54:10,672] INFO add 1 failed batches (com.splunk.kafka.connect.SplunkSinkTask:322) [2019-02-21 14:54:10,672] INFO total failed batches 263 (com.splunk.kafka.connect.SplunkSinkTask:47) [2019-02-21 14:54:10,672] ERROR failed to send batch (com.splunk.kafka.connect.SplunkSinkTask:261) com.splunk.hecclient.HecException: All channels have back pressure at com.splunk.hecclient.LoadBalancer.send(LoadBalancer.java:62) at com.splunk.hecclient.Hec.send(Hec.java:233) at com.splunk.kafka.connect.SplunkSinkTask.send(SplunkSinkTask.java:257) at com.splunk.kafka.connect.SplunkSinkTask.handleFailedBatches(SplunkSinkTask.java:127) at com.splunk.kafka.connect.SplunkSinkTask.put(SplunkSinkTask.java:62) at org.apache.kafka.connect.runtime.WorkerSinkTask.deliverMessages(WorkerSinkTask.java:495) at org.apache.kafka.connect.runtime.WorkerSinkTask.poll(WorkerSinkTask.java:288) at org.apache.kafka.connect.runtime.WorkerSinkTask.iteration(WorkerSinkTask.java:198) at org.apache.kafka.connect.runtime.WorkerSinkTask.execute(WorkerSinkTask.java:166) at org.apache.kafka.connect.runtime.WorkerTask.doRun(WorkerTask.java:170) at org.apache.kafka.connect.runtime.WorkerTask.run(WorkerTask.java:214) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) I have restarted and reset the sink connector configuration. It is still spitting out this error after an hour. NOTE: This setup has been working for almost 2 weeks. It has only started doing this today. It did do this about 5 days ago. It came up with the same error and then corrected itself. Thanks! ... View more
