[jira] [Created] (HDDS-4095) Byteman script to debug HCFS
performance
Marton Elek created HDDS-4095:
---------------------------------
Summary: Byteman script to debug HCFS performance
Key: HDDS-4095
URL: https://issues.apache.org/jira/browse/HDDS-4095
Project: Hadoop Distributed Data Store
Issue Type: Improvement
Reporter: Marton Elek
Assignee: Marton Elek
Teragen with Ozone is reported to be slower with Ozone than Hdfs with some specific configuration.
To make it easier to compare different file system, we need an easy measurement on the same point (FSDataOutputStream.write) to compare the time spent in that method with Hdfs/Ozone/other file systems.
It can be done with a byteman instrumentation rule
