Daniel Pol commented on HDFS-8198: ---------------------------------- [~eddyxu] Key work being "should". checknative shows ISA-L is loaded but I don't see any performance difference between running with rs_native vs rs_java. So I'm wondering if it's really using the coder I specify. Even with DEBUG log level, the map output for Teragen shows both rs_native and rs_java is loaded, but no clear way to know which one is used. Even with the io.erasurecode.codec.rs.rawcoders set to one of these coders only, I still see the same debug message. Was wondering if there's some output with DEBUG or INFO log level that would give me a hint which coder is using. Would be even better if there was a DEBUG message that shows exactly which coder is used for EC encoding. > Erasure Coding: system test of TeraSort > --------------------------------------- > > Key: HDFS-8198 > URL: https://issues.apache.org/jira/browse/HDFS-8198 > Project: Hadoop HDFS > Issue Type: Sub-task > Affects Versions: HDFS-7285 > Reporter: Kai Sasaki > Attachments: ec.out, replication.out > > > Functional system test of TeraSort on EC files. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
