Description

HttpFs supports only the permissions: [0-7][0-7][0-7]

In order to be compatible with webhdfs in needs to understand octal and sticky bit permissions (e.g. 0777, 01777...)

Example of error:
curl -L -X PUT "http://localhost:14000/webhdfs/v1/user/romain/test?permission=01777&op=SETPERMISSION&user.name=romain"
{"RemoteException":{"message":"java.lang.IllegalArgumentException: Parameter [permission], invalid value [01777], value must be [default|(-[-r][-w][-x][-r][-w][-x][-r][-w][-x])|[0-7][0-7][0-7]]","exception":"QueryParamException","javaClassName":"com.sun.jersey.api.ParamException$QueryParamException"}}

Works with WebHdfs:
curl -L -X PUT "http://localhost:50070/webhdfs/v1/user/romain/test?permission=01777&op=SETPERMISSION&user.name=romain"
echo $?
0

curl -L -X PUT "http://localhost:14000/webhdfs/v1/user/romain/test?permission=999999&op=SETPERMISSION&user.name=romain"
{"RemoteException":

{"message":"java.lang.IllegalArgumentException: Parameter [permission], invalid value [999999], value must be [default|(-[-r][-w][-x][-r][-w][-x][-r][-w][-x])|[0-7][0-7][0-7]]","exception":"QueryParamException","javaClassName":"com.sun.jersey.api.ParamException$QueryParamException"}
