Subject [jira] [Commented] (HDFS-9538) libhdfs++: load configuration from files
Date Mon, 14 Dec 2015 18:22:46 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9538?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15056421#comment-15056421

James Clampffer commented on HDFS-9538:

A couple more comments:

-nftw_remove calls perror to handle error conditions.  Should this have an #ifdef in case
the user doesn't want things being printed to stderr?
-The return code for the mkdir call in TempDir::Tempdir() is never checked.  Should this have
a check that clears out path, or bails if path is already empty, in case of permissions issues?

> One goal of the Configuration classes are to allow the consumers of the libhdfs++ library
to deploy client applications into hadoop edge nodes and have them pick up the Hadoop configuration
that has been deployed there.
> Note that we also need to support the use case where the consumer application will manage
Hadoop configuration files itself, or will handle all configuration out-of-band.
> libhdfs++ should be able to read files that are found in the field and easily construct
an instance that will communicate with the cluster.
