Daryn Sharp commented on HDFS-3577: ----------------------------------- +1 Looks good to me! Might want to alter the description to indicate it's fixing the problem of making new connections for every chunk and exhausting fds. > WebHdfsFileSystem can not read files larger than 24KB > ----------------------------------------------------- > > Key: HDFS-3577 > URL: https://issues.apache.org/jira/browse/HDFS-3577 > Project: Hadoop HDFS > Issue Type: Bug > Components: hdfs client > Affects Versions: 0.23.3, 2.0.0-alpha > Reporter: Alejandro Abdelnur > Assignee: Tsz Wo (Nicholas), SZE > Priority: Blocker > Attachments: h3577_20120705.patch, h3577_20120708.patch, > h3577_20120714.patch, h3577_20120716.patch, h3577_20120717.patch > > > If reading a file large enough for which the httpserver running > webhdfs/httpfs uses chunked transfer encoding (more than 24K in the case of > webhdfs), then the WebHdfsFileSystem client fails with an IOException with > message *Content-Length header is missing*. > It looks like WebHdfsFileSystem is delegating opening of the inputstream to > *ByteRangeInputStream.URLOpener* class, which checks for the *Content-Length* > header, but when using chunked transfer encoding the *Content-Length* header > is not present and the *URLOpener.openInputStream()* method thrown an > exception. -- This message is automatically generated by JIRA.
