[~sdeka]=C2=A0 Please go ahead with the patch, th= ank you for addressing this issue. > Performance test infrastructure : skip writing user data on Datanode > -------------------------------------------------------------------- > > Key: HDDS-1094 > URL: https://issues.apache.org/jira/browse/HDDS-1094 > Project: Hadoop Distributed Data Store > Issue Type: Improvement > Components: Ozone Datanode > Reporter: Supratim Deka > Assignee: Supratim Deka > Priority: Major > Labels: pull-request-available > Time Spent: 1h 20m > Remaining Estimate: 0h > > Goal: > It can be useful to exercise the IO and control paths in Ozone for simula= ted large datasets without having huge disk capacity at hand. For example, = this will allow us to get things like container reports and incremental con= tainer reports, while not needing huge cluster capacity. The [SimulatedFsDa= taset|https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoo= p-hdfs/src/test/java/org/apache/hadoop/hdfs/server/datanode/SimulatedFSData= set.java] does something similar in HDFS. It has been an invaluable tool to= simulate large data stores. -- This message was sent by Atlassian Jira (v8.3.2#803003) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: hdfs-issues-help@hadoop.apache.org
