--------------------------------------
Assignee: Sadanand Shenoy
> 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
> Assignee: Sadanand Shenoy
> Priority: Major
>
> 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.
