Hi all, I have two recurring errors with Accumulo in my cluster and I would like to know more about them. The first, usually happening at ingestion time when I write with the batch writers many records, is the "Running low on memory". We keep adding memory to Accumulo but this is a blind guess and I was wondering if there is a way to understand how much memory Accumulo would need considering the amount of data that will be written. Should we write slowly to Accumulo to avoid this? What is filling all the memory at ingestion time? Secondly, we have these zookeeper session expired and other zookeeper timeouts. Zookeeper on our cluster works quite well, we have many systems using it. How can I debug a "zookeeper session expired" in Accumulo?
