Issue:

In a heavily utilized kafka cluster AMS will keep on crashing with error

"ERROR org.apache.hadoop.hbase.client.AsyncProcess: Cannot get replica 0 location for {"totalColumns":5,"row":"kafka.server.FetcherLagMetrics."

Solution:

1. Run the following command to gather the amount of metrics being collected:

curl http://<Ambari-metrics-collector-host>:6188/ws/v1/timeline/metrics/metadata

2. From Ambari UI -> Kafka -> Configs -> Fliter

search for: "external.kafka.metrics.exclude.prefix"

3. Add the following at the end:

kafka.log.Log

4. Restart Kafka.

This will exclude additional metrics from getting captured and will increase the stability of the AMS.
