Tsz Wo Nicholas Sze commented on HDFS-7358: ------------------------------------------- > ... Could it release the buffer when it is done writing? ... I did it in some early patches but it did not work. The packet transfer might fail. When it fails, we need to re-send the packet. So that we cannot release buffer until we receive the ack. > Clients may get stuck waiting when using ByteArrayManager > --------------------------------------------------------- > > Key: HDFS-7358 > URL: https://issues.apache.org/jira/browse/HDFS-7358 > Project: Hadoop HDFS > Issue Type: Bug > Components: hdfs-client > Reporter: Tsz Wo Nicholas Sze > Assignee: Tsz Wo Nicholas Sze > Attachments: h7358_20141104.patch, h7358_20141104_wait_timeout.patch, > h7358_20141105.patch, h7358_20141106.patch, h7358_20141107.patch, > h7358_20141108.patch > > > [~stack] reported that clients might get stuck waiting when using > ByteArrayManager; see [his > comments|https://issues.apache.org/jira/browse/HDFS-7276?focusedCommentId=14197036&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14197036]. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
