Wei-Chiu Chuang created HDFS-17080: -------------------------------------- Summary: Fix ec connection leak (GitHub PR#5807) Key: HDFS-17080 URL: https://issues.apache.org/jira/browse/HDFS-17080 Project: Hadoop HDFS Issue Type: Task Reporter: Wei-Chiu Chuang
Creating this jira to track GitHub PR #5807. {quote}Description of PR This PR fixes EC connection leak if got exception when constructing reader. How was this patch tested? Cluster: Presto Data: EC Query: select col from table(EC data) limit 10 Presto is a long time running process to deal with query. In this case, when it gets 10 records, it will interrupt other threads. Other threads may be in constructing reader or getting next record. If getting next record is interrupted, it will be caught and Presto will close it. But if constructing reader is interrupted, Presto cannot close it because reader in Presto has not been created. So we can observe whether EC connection is closed when doing EC limit query. Use netstat command.{quote} -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
