Eli Collins updated HDFS-1001: ------------------------------ Attachment: HDFS-1001-6.patch Attached a patch fixes a warning in the last patch. > DataXceiver and BlockReader disagree on when to send/recv CHECKSUM_OK > --------------------------------------------------------------------- > > Key: HDFS-1001 > URL: https://issues.apache.org/jira/browse/HDFS-1001 > Project: Hadoop HDFS > Issue Type: Bug > Components: data-node > Reporter: bc Wong > Assignee: bc Wong > Priority: Minor > Fix For: 0.23.0 > > Attachments: HDFS-1001-2.patch, HDFS-1001-3.patch, HDFS-1001-3.patch, > HDFS-1001-4.patch, HDFS-1001-5.patch, HDFS-1001-6.patch, > HDFS-1001-rebased.patch, HDFS-1001.patch, HDFS-1001.patch.1 > > > Running the TestPread with additional debug statements reveals that the > BlockReader sends CHECKSUM_OK when the DataXceiver doesn't expect it. > Currently it doesn't matter since DataXceiver closes the connection after > each op, and CHECKSUM_OK is the last thing on the wire. But if we want to > cache connections, they need to agree on the exchange of CHECKSUM_OK. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
