> Project: Kudu
> Issue Type: Bug
> Components: fs
> Reporter: Jean-Daniel Cryans

> Noticed on a cluster that runs YCSB non-stop in a loop, using a new table
> each time and deleting an old one, while ensuring that it keeps at least 10
> tables to simulate a "loaded" cluster.
> After a few weeks of running, the cluster's file descriptor usage started
> triggering alerts in the monitoring system. The total data consumption never
> really changes since we keep at most 10 tables. Todd found that we have
> thousands of really small log block manager containers.
> The workaround at the moment is to simply increase the ulimit for open file
> descriptors.
