> Key: HDFS-9286
> URL: https://issues.apache.org/jira/browse/HDFS-9286
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: HDFS
> Affects Versions: 2.6.0
> Reporter: Wei-Chiu Chuang
> Assignee: Wei-Chiu Chuang
> Fix For: 2.8.0
>
> Attachments: HDFS-9286.001.patch, HDFS-9286.002.patch

> Output from WebHdfs:
> curl -X PUT
> "http://weichiu.vpc.cloudera.com:50070/webhdfs/v1/a?aclspec=group:user:&op=REMOVEACLENTRIES&user.name=weichiu";
> Output from HttpFs:
> curl -X PUT
> "http://weichiu.vpc.cloudera.com:14000/webhdfs/v1/a?aclspec=group:user:&op=REMOVEACLENTRIES&user.name=weichiu";
> {"RemoteException":{"message":"Invalid <aclSpec> :
> group:user:","exception":"HadoopIllegalArgumentException","javaClassName":"org.apache.hadoop.HadoopIllegalArgumentException"}}
> The exception is thrown because the ACL string "group:user:" is not
> recognized by HttpFs.
> Effectively, what this means is that the behavior of HttpFs is not consistent
> with that of WebHdfs.
> Additionally, command line does accept the ACL string. For example:
> hdfs dfds -setfactl -x group:yyy: /a
> Bug is reproducible if httpfs and acl are enabled, and reproducible on
> single-node cluster configuration.
> To reproduce, add into core-site.xml:
> <property>
> <name>dfs.webhdfs.enabled</name>
> <value>true</value>
> </property>
> <property>
> <name>dfs.namenode.acls.enabled</name>
> <value>true</value>
> </property>
> <property>
> <name>hadoop.proxyuser.#HTTPFSUSER#.hosts</name>
> <value>httpfs-host.foo.com</value>
> </property>
> <property>
> <name>hadoop.proxyuser.#HTTPFSUSER#.groups</name>
> <value>*</value>
> </property>
> restart name node, data node and httpfs daemon
