[jira] [Updated] (HADOOP-8885) Need to add fs shim to use QFS
[ https://issues.apache.org/jira/browse/HADOOP-8885?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
thilee updated HADOOP-8885:
---------------------------
Attachment: HADOOP-8885-branch-1.patch
Attached is the patch for *branch-1*.
In addition to applying the patch, you would need to do two things:
(1) To compile: you need to copy the qfs access JAR (qfs-<version>.jar) to the branch-1 _lib_ directory.
(2) To run: you need to have the directory of libqfs*.so in your {{LD_LIBRARY_PATH}}.
The tarball containing the JAR file and the shared libraries can be downloaded here: (please download the one that matches your platform, untar and look inside _lib_ directory)
[https://github.com/quantcast/qfs/wiki/Binary-Distributions]
The JAR file should eventually be integrated to Apache Hadoop, under _lib_ directory, as qfs-1.0.0.jar.
