Benoit Perroud updated HADOOP-16728: ------------------------------------ Labels: SFTP (was: ) > SFTPFileSystem connection pool not reusing connections properly > --------------------------------------------------------------- > > Key: HADOOP-16728 > URL: https://issues.apache.org/jira/browse/HADOOP-16728 > Project: Hadoop Common > Issue Type: Bug > Components: fs > Affects Versions: 3.2.1 > Reporter: Benoit Perroud > Priority: Major > Labels: SFTP > > This issue is trying to address few issues in the SFTP filesystem, and > especially in SFTPConnectionPool: > * all channels for a given connectionInfo are removed from the pool instead > of only the selected channel. > * Closed connections are added back into the pool. They should be filtered > out. > * The SFTPInputStream is closing the stream instead of returning it into the > pool. > * Some connection leak could happen in some cases > As a result, if you have multiple threads sharing the pool, the SFTP > filesystem is underperforming by untimely re-establishing SSH connections. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
