Subject [jira] [Updated] (HDFS-8766) Implement a libhdfs(3) compatible API
Date Wed, 28 Oct 2015 15:04:27 GMT

     [ https://issues.apache.org/jira/browse/HDFS-8766?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

James Clampffer updated HDFS-8766:
----------------------------------
    Attachment: HDFS-8766.HDFS-8707.011.patch

Should have all the fixes for your last comment Haohui:
-Updated the style for block comments.
-Moved the hdfs_internal and hdfsFile_internal implementations into the same file as the C
API functions because they shouldn't be visible elsewhere anyway.  This also got the "include
namespace hdfs" out of the header.
-All promises are made using make_shared, the lambda captures the shared_ptr by value to bump
the reference count to prevent the race condition.

> 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.
