Eric Payne updated HDFS-7163:
-----------------------------
Attachment: HDFS-7163.002.patch
New patch (HDFS-7163.002.patch). Fixed unit test failures for
{{TestWriteReadStripedFile}}. Also fixed javadoc and whitespace warnings.
The following tests did not fail for me in my build environment, so I don't
think they are related:
{{hadoop.hdfs.server.balancer.TestBalancerWithMultipleNameNodes}}
{{hadoop.hdfs.server.blockmanagement.TestNodeCount}}
{{hadoop.hdfs.server.namenode.ha.TestDNFencing}}
{{hadoop.hdfs.server.namenode.TestCacheDirectives}}
{{hadoop.hdfs.TestDFSStripedOutputStreamWithFailure000}}
I will shortly post branch-2 and branch-2.7 patches.
> WebHdfsFileSystem should retry reads according to the configured retry policy.

> Key: HDFS-7163
> URL: https://issues.apache.org/jira/browse/HDFS-7163
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: webhdfs
> Affects Versions: 3.0.0, 2.5.1
> Reporter: Eric Payne
> Assignee: Eric Payne
> Attachments: HDFS-7163.001.patch, HDFS-7163.002.patch, WebHDFS Read
> Retry.pdf
>
>
> In the current implementation of WebHdfsFileSystem, opens are retried
> according to the configured retry policy, but not reads. Therefore, if a
> connection goes down while data is being read, the read will fail and the
> read will have to be retried by the client code.
> Also, after a connection has been established, the next read (or seek/read)
> will fail and the read will have to be restarted by the client code.
