Hudson commented on HDFS-6549: ------------------------------ FAILURE: Integrated in Hadoop-Hdfs-trunk #1780 (See [https://builds.apache.org/job/Hadoop-Hdfs-trunk/1780/]) HDFS-6549.

Myers > Assignee: Aaron T. Myers > Fix For: 2.5.0 > > Attachments: HDFS-6549.patch, HDFS-6549.patch, HDFS-6549.patch > > > We've identified two issues when trying to access the HDFS NFS Gateway from > an AIX NFS client: > # In the case of COMMITs, the AIX NFS client will always send 4096, or a > multiple of the page size, for the offset to be committed, even if fewer > bytes than this have ever, or will ever, be written to the file. This will > cause a write to a file from the AIX NFS client to hang on close unless the > size of that file is a multiple of 4096. > # In the case of READDIR and READDIRPLUS, the AIX NFS client will send the > same cookie verifier for a given directory seemingly forever after that > directory is first accessed over NFS, instead of getting a new cookie > verifier for every set of incremental readdir calls. This means that if a > directory's mtime ever changes, the FS must be unmounted/remounted before > readdir calls on that dir from AIX will ever succeed again. > From my interpretation of RFC-1813, the NFS Gateway is in fact doing the > correct thing in both cases, but we can introduce simple changes on the NFS > Gateway side to be able to optionally work around these incompatibilities. -- This message was sent by Atlassian JIRA (v6.2#6252)
