No reason why this can't be backported to branch-3.2; > 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 > Assignee: Sahil Takiar > Priority: Major > Fix For: 3.3.0 > > > 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 (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
