Subject [jira] [Commented] (HDFS-8766) Implement a libhdfs(3) compatible API
Date Sat, 03 Oct 2015 00:20:26 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8766?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14941988#comment-14941988
] 

Haohui Mai commented on HDFS-8766:
----------------------------------

bq. I added a simple timeout to clear out the bad datanodes after a specified period of time
(default to 2 minutes). I think that should be sufficient for the initial API

The default timeout is 10 minutes and the timeout should be bounded to every single data node.
This functionality requires a specific gmock test.

I think it makes sense to separate the integration test to an another jira.

> Add a synchronous API that is compatible with the hdfs.h header used in libhdfs and libhdfs3.
 This will make it possible for projects using libhdfs/libhdfs3 to relink against libhdfspp
with minimal changes.
> This also provides a pure C interface that can be linked against projects that aren't
built in C++11 mode for various reasons but use the same compiler.  It also allows many other
programming languages to access libhdfspp through builtin FFI interfaces.
> The libhdfs API is very similar to the posix file API which makes it easier for programs
built using posix filesystem calls to be modified to access HDFS.
