Subject [jira] [Updated] (HDFS-8766) Implement a libhdfs(3) compatible API
Date Wed, 28 Oct 2015 22:02:27 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-8707.012.patch

Added brackets to if blocks.  Got all the error formatting stuff out of the header. pushed
ReportError into hdfs.cc and set it up to conditionally print errno and messages based on
a debug symbol similar to what asio does.

> 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.
