Padma Penumarthy created DRILL-4867: ---------------------------------------
Summary: Scan fragment placement algorithm for parquet is not taking partition pruning into consideration Key: DRILL-4867 URL: https://issues.apache.org/jira/browse/DRILL-4867 Project: Apache Drill Issue Type: Bug Components: Execution - Flow Affects Versions: 1.8.0 Reporter: Padma Penumarthy Assignee: Padma Penumarthy Priority: Critical Drill decides how many scan fragments to run on each node based on endpoint affinity (ratio of number of bytes on the host/total bytes for the whole scan) of the node. But, pruned rowGroups are not removed from the calculation. This messes up placement of scan fragment and can cause remote reads. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
