Summary: S3AInputStream to implement CanUnbuffer Key: HADOOP-14747 URL: https://issues.apache.org/jira/browse/HADOOP-14747 Project: Hadoop Common Issue Type: Sub-task Components: fs/s3 Affects Versions: 2.8.1 Reporter: Steve Loughran HBase relies on FileSystems implementing {{CanUnbuffer.unbuffer()}} to force input streams to free up remote connections (HBASE-9393). This works for HDFS, but not elsewhere. S3A input stream can implement {{CanUnbuffer.unbuffer()}} by closing the input stream and relying on lazy seek to reopen it on demand. Needs * Contract specification of unbuffer. As in "who added a new feature to filesystems but forgot to mention what it should do?" * Contract test for filesystems which declare their support. * S3AInputStream to call {{closeStream()}} on a call to {{unbuffer()}}. * Test case -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
