[Hadoop Wiki] Update of "BuildFuseDfs023" by PetruDimulescu
Dear Wiki user,
You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.
The "BuildFuseDfs023" page has been changed by PetruDimulescu:
http://wiki.apache.org/hadoop/BuildFuseDfs023
New page:
= Build FuseDfs on 0.23 and higer =
I submitted a patch with https://issues.apache.org/jira/browse/HDFS-2696 which if integrated would render most of this page obsolete.
If you want to build fuse-dfs on 0.23 snapshot branch, on ubuntu linux 11.10 (important, as you'll see:)
First you need to do a
$ mvn package -Pnative
in hadoop-common/hadoop-hdfs-project/hadoop-hdfs. You'll get a target/native/ subdir, go there and do a make install so that you'll have libhdfs.so in a system libdir.
Then I went to hadoop-hdfs/src/contrib and typed:
$ ant compile -Dfusedfs=1
it complained about not having
hadoop-common/hadoop-hdfs-project/hadoop-hdfs/ivy/libraries.properties
-- that (empty) file is in hadoop-common/hadoop-hdfs-project/hadoop-hdfs/src/contrib/fuse-dfs/ivy/libraries.properties).
After I copied it in the expected place, I got :
{{{
[exec] In file included from fuse_impls.h:26:0,
[exec] from fuse_dfs.c:21:
[exec] fuse_context_handle.h:22:18: fatal error: hdfs.h: No such
file or directory
}}}
If I copied hdfs.h from the src/main/native dir to /usr/local/include,
just to make it happy quickly. Next error:
{{{
[exec] fuse_impls_write.c: In function 'dfs_write':
[exec] fuse_impls_write.c:38:16: warning: cast to pointer from
integer of different size [-Wint-to-pointer-cast]
[exec] fuse_dfs.o: In function `is_protected':

/home/petru/work/ubeeko/hadoo.apache.org/0.23/hadoop-common/hadoop-hdfs-project/hadoop-hdfs/src/contrib/fuse-dfs/src/fuse_dfs.c:27:
undefined reference to `fuse_get_context'
}}}
This is because of this:
https://bugs.launchpad.net/ubuntu/+source/fuse/+bug/878612
so just edit the failing linking command which something like this :
{{{
gcc -Wall -g -Wall -O3
-L/home/petru/work/ubeeko/hadoo.apache.org/0.23/hadoop-common/hadoop-hdfs-project/hadoop-hdfs/build/c++/Linux-i386-32/lib
-lhdfs -L/lib -lfuse -L/usr/local/java/jdk/jre/lib/i386/server -ljvm -o
fuse_dfs fuse_dfs.o fuse_options.o fuse_trash.o fuse_stat_struct.o
fuse_users.o fuse_init.o fuse_connect.o fuse_impls_access.o
fuse_impls_chmod.o fuse_impls_chown.o fuse_impls_create.o
fuse_impls_flush.o fuse_impls_getattr.o fuse_impls_mkdir.o
fuse_impls_mknod.o fuse_impls_open.o fuse_impls_read.o

fuse_impls_truncate.o fuse_impls_utimens.o fuse_impls_unlink.o
fuse_impls_write.o
}}}
by moving all the -L and -l part at the end, then:
{{{
