I am new to Druid. We have druid installed on single machine with default configurations, and trying to load data to Druid from Kafka. We are able to load data to druid using the supervisor spec submitted, but we face intermittent task failures with following errors
Error while loading multiple records(one at a time, but trying to load many records in a timeframe to asses the performance) org.apache.druid.indexing.seekablestream.SeekableStreamIndexTaskRunner - Encountered exception while running task.
Caused by: java.lang.OutOfMemoryError’. This error happens very frequently and we could see plenty of failed index_kafka tasks in overlord console.
Could you please share some insight on how to fix these errors. Please advise if additional information that will help the analysis
