-------------------------------------
Summary: HttpFs does not parse ACL syntax correctly for operation
REMOVEACLENTRIES
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
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"}}
Effectively, what this means is that the behavior of HttpFs is not consistent
with that of WebHdfs.
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
