Subject [jira] [Commented] (HDFS-12950) oiv will fail in secure cluster
Date Thu, 21 Dec 2017 16:57:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12950?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16300273#comment-16300273

Brahma Reddy Battula commented on HDFS-12950:

bq.This jira is related to oiv and in the example you are issuing ls command.
when we execute {{"hdfs oiv -i fsimage"}}, It launches a HTTP server that exposes read-only
WebHDFS API.Here default port is {{5978}}.So I used same to list the files. Please refer example
for more.
bq.I tried the same command on 2.8 cluster and I am getting some different error.
looks with {{5978}} nothing is running,so it's retrying.
bq.Also can you mention the "Affects Version" ?
It's applicable to {{2.6}} + all the versions,will update same..

> if we execute ls, it will throw following.
> {noformat}
> hdfs dfs -ls webhdfs://
> ls: Invalid value for webhdfs parameter "op"
> {noformat}
> When client is configured with security (i.e "hadoop.security.authentication= KERBEROS)
> then webhdfs will request getdelegation token which is not implemented and hence it will
 throw “ls: Invalid value for webhdfs parameter "op"”.
