Ranith Sardar commented on HIVE-25381: -------------------------------------- hive code is getting used for impersonating {code} public static boolean isOwnerOfFileHierarchy(final FileSystem fs, final FileStatus fileStatus, final String userName, final boolean recurse) throws IOException, InterruptedException { UserGroupInformation proxyUser = UserGroupInformation.createProxyUser(userName, UserGroupInformation.getLoginUser()); try { boolean isOwner = proxyUser.doAs(new PrivilegedExceptionAction<Boolean>() { @Override public Boolean run() throws Exception { FileSystem fsAsUser = FileSystem.get(fs.getUri(), fs.getConf()); return checkIsOwnerOfFileHierarchy(fsAsUser, fileStatus, userName, recurse); } }); return isOwner; } finally { FileSystem.closeAllForUGI(proxyUser); }{code} Here userName is coming from {code:java} String configuredOwner = HiveConf.getVar(conf, ConfVars.HIVE_LOAD_DATA_OWNER);{code} which basically means UserGroupInformation.getLoginUser() is impersonating "userName". > Hive impersonation Failed when load data of managed tables set as hive > ---------------------------------------------------------------------- > > Key: HIVE-25381 > URL: https://issues.apache.org/jira/browse/HIVE-25381 > Project: Hive > Issue Type: Bug > Reporter: Ranith Sardar > Assignee: Ranith Sardar > Priority: Minor > Fix For: 3.1.0, 4.0.0 > > > When hive.server2.enable.doAs = True and setting hive as the default value > for "hive.load.data.owner" property, this will cause below logic(in > Hive.java-needToCopy{color:#24292e}({color})) to fail always as the > framework is validating the owner of the file against the value which we set > in the property hive.load.data.owner. -- This message was sent by Atlassian Jira (v8.3.4#803005)
