>                 Key: HDFS-9286
>                 URL: https://issues.apache.org/jira/browse/HDFS-9286
>             Project: Hadoop HDFS
>          Issue Type: Bug

> 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
