Weiwei Yang commented on HDFS-11189: ------------------------------------ Hi [~guadilla] If you have an error stack trace, that will help to explain the problem. At mean time I am running out of idea about what would be the root cause of this issue, I cannot make any fix if the issue can not be reproduced. I'll let others see if they have any more ideas. > WebHDFS and FollowRedirects > --------------------------- > > Key: HDFS-11189 > URL: https://issues.apache.org/jira/browse/HDFS-11189 > Project: Hadoop HDFS > Issue Type: Bug > Components: webhdfs > Affects Versions: 2.7.3 > Environment: We are using webhdfs from a j2ee environment with java > 6. In the web application we have a lot of libraries: spring, jersey, > jackson... > Reporter: Oscar Guadilla > Attachments: WebHdfsFileSystem.java > > > In some cases with simple operations (get file - non two step operation) we > detect that FollowRedirects flag of http comes as "false" and it makes > webhdfs crash. > We don't really know which library change this behavior and it is really > strange because the change is done directly in the jvm because in other > wars/ears of the same j2ee server it fails also. If we restart the j2ee > server it starts working again. > To fix the problem we changed the WebHdfsFileSystem class adding > "setInstanceFollowRedirects(true)" in the connection management instead of > supposing that it should be true and it works fine. > The same problem arises both in 1.x and 2.x webhdfs. We didn't test in 3.x > Could you fix it? We did it in our environment but it would fine in it could > be included in the next releases. > Thanks in advance, > Oscar -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
