--------------------------------------
Summary: Add a config to set max_open_files for OM RocksDB.
Key: HDDS-11191
URL: https://issues.apache.org/jira/browse/HDDS-11191
Project: Apache Ozone
Issue Type: Bug
Components: OM
Reporter: Sadanand Shenoy
Currently the max_open_files rocksdb config is -1 by default and not set
anywhere via Ozone code. However in situations where the number of SST Files in
the rocksdb instance becomes greater than the ulimit (open file limit of the
OS), Rocksdb will not respect the OS config and try to open all files at once
thereby leading to "Too many files" error.
Introducing a config in Ozone to set this is helpful to avoid/recover from such
crashes.
