> We have a Drill cluster with 20+ Nodes and we store all history profiles in hdfs. Without
doing periodically cleans for hdfs, the profiles page gets slower while serving more queries.
> Code from LocalPersistentStore.java uses fs.list(false, basePath) for fetching the latest
100 history profiles by default, I guess this operation blocks the page loading (Millions
small files can be stored in the basePath), maybe we can try some other ways to reach the
same goal.
