chuanjie.duan updated RANGER-1992:
----------------------------------
Description:
user 'cim_beta_db' create directory in user 'dataswap' parent directory as below
hdfs dfs -ls /user/hive/warehouse/dataswap.db/
drwxrwx- -- - cim_beta_db dataswap 0 2018-02-26 09:49
/user/hive/warehouse/dataswap.db/test
drwxrwx- -- - dataswap dataswap /user/hive/warehouse/dataswap.db
drwxrwx- -x- dataswap dataswap /user/hive/warehouse
I add hdfs policy, user 'cim_beta_db' ‘’execute‘’ permission to path
/user/hive/warehouse/dataswap.db
hdfs dfs -ls /user/hive/warehouse/dataswap.db/test
ls: Permission denied: user=cim_beta_db, access=EXECUTE,
inode="/user/hive/warehouse/dataswap.db/test":{color:#ff0000}dataswap{color}:dataswap:drwxrwx---
there are two issue.
# exception information should
inode="/user/hive/warehouse/dataswap.db":{color:#ff0000}dataswap{color}:dataswap:drwxrwx---
# policy cannot combine use, policy match failed, would check default
permission only, even if parent directory give a 'execute' permission
// checkINodeAccess
if(authzStatus == AuthzStatus.ALLOW && access != null && inode != null) {
LOG.info("checkINodeAccess");
INodeAttributes inodeAttribs = inodeAttrs.length > 0 ?
inodeAttrs[inodeAttrs.length - 1] : null;
authzStatus = isAccessAllowed(inode, inodeAttribs, access, user, groups,
plugin, auditHandler);
if (authzStatus == AuthzStatus.NOT_DETERMINED) {
authzStatus = {color:#FF0000}checkDefaultEnforcer{color}(fsOwner, superGroup,
ugi, inodeAttrs, inodes,
pathByNameArr, snapshotId, path, ancestorIndex, doCheckOwner,
FsAction.NONE, FsAction.NONE, access, FsAction.NONE, ignoreEmptyDir,
isTraverseOnlyCheck, ancestor, parent, inode, auditHandler);
}
}
was:
hdfs dfs -ls /user/hive/warehouse/dataswap.db/
drwxrwx-- -- cim_beta_db dataswap 0 2018-02-26 09:49
/user/hive/warehouse/dataswap.db/test
hdfs dfs -ls /user/hive/warehouse/dataswap.db/test
ls: Permission denied: user=cim_beta_db, access=EXECUTE,
inode="/user/hive/warehouse/dataswap.db/test":{color:#ff0000}dataswap{color}:dataswap:drwxrwx---
user should be cim_beta_db, maybe it's a hdfs bug
