> Running over extended period (48+ hrs), we've noticed HiveServer2 leaking FileSystem
objects in FileSystem.CACHE. Linked jiras were previous attempts to fix it, but the issue
still seems to be there. A workaround is to disable the caching (by setting {{fs.hdfs.impl.disable.cache}}
and {{fs.file.impl.disable.cache}} to {{true}}), but creating new FileSystem objects is expensive.
