[jira] [Updated] (HDFS-3110) libhdfs implementation of direct read API

     [ https://issues.apache.org/jira/browse/HDFS-3110?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Henry Robinson updated HDFS-3110:
---------------------------------

    Attachment: HDFS-3110.1.patch

Here's a patch with a simple smoke test. I have also reworked test-libhdfs.sh to work against trunk, since it had not been updated since the days of the ant build. 

After setting HADOOP_HOME, running test-libhdfs.sh spins up a mini cluster (from HDFS-3167) and runs the tests correctly for me from a checkout of trunk. This is a better situation than before, even though the script is not yet integrated with the automatic build (there is a todo in the hdfs pom.xml for this).

Let me know if I should split the refactor of the test script up from this JIRA.

> Once HDFS-2834 gets committed, we can add support for the new API to libhdfs, which leads to significant performance increases when reading local data from C.
