Ashutosh Gupta commented on HADOOP-17177: ----------------------------------------- [~ste...@apache.org] - I have been playing/working on java 11 since last few months and have seen some *serious performance degradation, On Java 11 -* Tera gen took 4 minutes, and 32 seconds as compared to 3 minutes, and 28 seconds on Java 8. Tera sort took 10 minutes, and 55 seconds on Java 11 compared to 8 min 32 sec on Java 8. Any ideas/suggestions on this? Did you guys face the same issue. Also tried various things like changing the GC etc but nothing has really helped in performance improvement yet. > Java 17 support > --------------- > > Key: HADOOP-17177 > URL: https://issues.apache.org/jira/browse/HADOOP-17177 > Project: Hadoop Common > Issue Type: Improvement > Components: build > Reporter: Akira Ajisaka > Assignee: Ashutosh Gupta > Priority: Major > > Umbrella JIRA to support Java 17 LTS. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
