Shilun Fan updated HDFS-16982: ------------------------------ Target Version/s: 3.4.0 Affects Version/s: 3.4.0 > Use the right Quantiles Array for Inverse Quantiles snapshot > ------------------------------------------------------------- > > Key: HDFS-16982 > URL: https://issues.apache.org/jira/browse/HDFS-16982 > Project: Hadoop HDFS > Issue Type: Bug > Components: datanode, metrics > Affects Versions: 3.4.0 > Reporter: Ravindra Dingankar > Assignee: Ravindra Dingankar > Priority: Minor > Labels: pull-request-available > Fix For: 3.4.0 > > > HDFS-16949 introduced InverseQuantiles. However during snapshot for Inverse > Quantiles we were still trying to access values from previous snapshot based > on the Quantile Array declared in MutableQuantiles. ( Quantile(.50, .050), > Quantile(.75, .025), Quantile(.90, .010), Quantile(.95, .005), Quantile(.99, > .001) ) > For InverseQuantiles we wont have these values ( except for Quantile(.50, > .050) ) thus except for 50 Percentile snapshot wont return any value for the > remaining quantiles. > Fix is to use the correct Quantiles Array to retrieve values during snapshot. > The new UTs verify this behavior. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
