Subject [jira] [Updated] (HDFS-2040) Only build libhdfs if a flag is passed
Date Mon, 06 Jun 2011 23:09:59 GMT

     [ https://issues.apache.org/jira/browse/HDFS-2040?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Eli Collins updated HDFS-2040:

    Attachment: hdfs-2040-1.patch

Patch attached:
* Removes the auto-setting of libhdfs
* Modifies bin-package to work even if the lib dir does not exist (eg because libhdfs has
not been build), and to use the platform-agnostic lib symlink

> In HDFS-2022 we made ant binary build libhdfs unconditionally, this is a pain for users
who now need to get the native toolchain working to create a tarball to test a change, and
inconsistent with common and MR (see MAPREDUCE-2559) which only build native code if a flag
is passed. Let's revert to the previous behavior of requiring -Dlibhdfs be passed at build
time. We could also create a new ant target that doesn't build the native code, however restoring
the old behavior seems simplest.
