Subject [jira] [Commented] (HDFS-2656) Implement a pure c client based on webhdfs
Date Tue, 11 Sep 2012 21:10:07 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2656?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13453420#comment-13453420
] 

Suresh Srinivas commented on HDFS-2656:
---------------------------------------

bq. I'm also a little surprised this was checked in w/o it actually building (HDFS-3909).
It is not built by Jenkins because of a need for a library. It has been manually tested as
you see in various benchmarks etc. posted.

> 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.
