             Summary: Add CLI option for checking if ISA-L accessible
                 Key: HDDS-9230
                 URL: https://issues.apache.org/jira/browse/HDDS-9230
             Project: Apache Ozone
          Issue Type: Improvement
            Reporter: Maksim Myskov
            Assignee: Maksim Myskov


ISA-L improves the performance of EC operations. Ozone uses Hadoop native library to discover ISA-L. However, the only way to check if ISA-L is loaded is to check logs for EC-related errors.
I propose to add a CLI command for checking if ISA-L is accessible. Hadoop checknative (see https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-common/NativeLibraries.html#Check) can be used as a reference.
