[GitHub] [hadoop-ozone] rakeshadr opened a new pull request #1160: HDDS-3900: Update default value of 'ozone.om.ratis.segment.size' and …

rakeshadr opened a new pull request #1160:
URL: https://github.com/apache/hadoop-ozone/pull/1160


   ## What changes were proposed in this pull request?
   Based on the OM write performance tests on **HDDs** - write heavy workload Synthetic NNLoadGenerator in single node HA, the default 16KB ratis segment size becomes the bottleneck which affects the OM performance.
   
   With 4MB segment size, single node OM HA write performance has improved and produced a performance gain of 2.2x times compares to non-HA on HDDs(phatcat machines).
   
   This jira recommends to update the default value to 4MB.
   
   ## What is the link to the Apache JIRA
   
   https://issues.apache.org/jira/browse/HDDS-3900
   
   ## How was this patch tested?
   Tested done in real cluster - phatcat machines using HDDs. Used Hadoop's Synthetic NNLoadGenerator benchmark tests.
