Subject [jira] [Commented] (HDFS-2656) Implement a pure c client based on webhdfs
Date Sun, 01 Apr 2012 03:10:19 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2656?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13243634#comment-13243634

donal zang commented on HDFS-2656:

Hi Zhanwei,
I'm interested in the c client.
But one thing I'm worrying about is the performance, since it uses http protocol.
Have you tested or thought about this?

> Currently, the implementation of libhdfs is based on JNI. The overhead of JVM seems a
little big, and libhdfs can also not be used in the environment without hdfs.
> It seems a good idea to implement a pure c client by wrapping webhdfs. It also can be
used to access different version of hdfs.
