> Improve error message from checkBlockLocalPathAccess
> ----------------------------------------------------
>
> Key: HDFS-10417
> URL: https://issues.apache.org/jira/browse/HDFS-10417
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: datanode
> Affects Versions: 2.7.2
> Reporter: Tianyin Xu
> Assignee: Tianyin Xu
> Priority: Minor
> Fix For: 2.8.0
>
> Attachments: HDFS-10417.000.patch, HDFS-10417.001.patch,
> HDFS-10417.002.patch
>
>
> The exception msg thrown by {{checkBlockLocalPathAccess}} is very specific to
> the implementation detail. It's really hard for users to understand it unless
> she reads and understands the code.
> The code is shown as follows:
> {code:title=org.apache.hadoop.hdfs.server.datanode.DataNode|borderStyle=solid}
> private void checkBlockLocalPathAccess() throws IOException {
> checkKerberosAuthMethod("getBlockLocalPathInfo()");
> String currentUser =
> UserGroupInformation.getCurrentUser().getShortUserName();
> if (!usersWithLocalPathAccess.contains(currentUser)) {
> throw new AccessControlException(
> "Can't continue with getBlockLocalPathInfo() "
> + "authorization. The user " + currentUser
> + " is not allowed to call getBlockLocalPathInfo");
> }
> }
> {code}
> (basically she needs to understand the code logic of getBlockLocalPathInfo)
> \\
> Note that {{usersWithLocalPathAccess}} is a *private final* purely coming
> from the configuration settings of {{dfs.block.local-path-access.user}},
> {code:title=org.apache.hadoop.hdfs.server.datanode.DataNode|borderStyle=solid}
> private final List<String> usersWithLocalPathAccess;
> ....
> this.usersWithLocalPathAccess = Arrays.asList(
>
> conf.getTrimmedStrings(DFSConfigKeys.DFS_BLOCK_LOCAL_PATH_ACCESS_USER_KEY));
> {code}
> In other word, the checking fails simply because the current user is not
> specified in the configuration setting of
> {{dfs.block.local-path-access.user}}. The log message should be much more
> clearer to make it easy for users to take actions, as demonstrated in the
> attached patch.
> Thanks!
