Chen Liang commented on HDFS-14058: ----------------------------------- Post some numbers from running DFSIO test, I ran the test for both with observer read enabled and without observer read, each with three runs. [^dfsio_crs.no-crs.txt] shows the results from the three runs with observer read disabled, while [^dfsio_crs.with-crs.txt] shows the results with observer read enabled. The numbers are very close. Again it is because the cluster is fairly empty so ANN alone is able to handle the read requests, in this case we don't gain much performance improvement by adding observer read. The test is to prove correctness and show there is no performance degradation. > Test reads from standby on a secure cluster with IP failover > ------------------------------------------------------------ > > Key: HDFS-14058 > URL: https://issues.apache.org/jira/browse/HDFS-14058 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: test > Reporter: Konstantin Shvachko > Assignee: Chen Liang > Priority: Major > Attachments: dfsio_crs.no-crs.txt, dfsio_crs.with-crs.txt > > > Run standard HDFS tests to verify reading from ObserverNode on a secure HA > cluster with {{IPFailoverProxyProvider}}. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
