Vlad Rozov updated DRILL-6164: ------------------------------ Labels: (was: ready-to-commit) > Heap memory leak during parquet scan and OOM > -------------------------------------------- > > Key: DRILL-6164 > URL: https://issues.apache.org/jira/browse/DRILL-6164 > Project: Apache Drill > Issue Type: Bug > Reporter: Vlad Rozov > Assignee: Vlad Rozov > Priority: Major > Fix For: 1.13.0 > > > During a scan of a large set of parquet files, Drill iterates over the set > initializing parquet readers. Such initialization may require a significant > memory usage (both heap and direct). When scan moves to the next parquet file > in the set, it does not remove reference to the reader from the set it > iterates over and does not remove references created during initialization. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
