Hi,

We are testing hdfs cluster and want to make it transparent to regular
storage users. Looks like fuse-dfs under contrib is a good solution.

Hadoop-0.20.2

I compile it with:
Jdk 1.6.0, both u13 and u20

(
java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Java HotSpot(TM) 64-Bit Server VM (build 16.3-b01, mixed mode)

java version "1.6.0_13"
Java(TM) SE Runtime Environment (build 1.6.0_13-b03)
Java HotSpot(TM) 64-Bit Server VM (build 11.3-b02, mixed mode)
)

Ant 1.8.0

It compiles ok but I cannot mount hdfs:
port=54310,server=hdfsnamenode
fuse-dfs didn't recognize /export/hdfs,-2
fuse-dfs ignoring option -d
fusermount: option allow_other only allowed if 'user_allow_other' is set in
/etc/fuse.conf

the fs.default.name for hadoop is:
<property>
  <name>fs.default.name</name>
  <value>hdfs://hdfsnamenode:54310</value>
  <description>test filesystem.</description>
</property>

I followed the instruction of a previous thread, (
http://mail-archives.apache.org/mod_mbox/hadoop-hdfs-user/201001.mbox/%[EMAIL PROTECTED]%3e),
but it doesn’t solve our problem.

Any idea? TIA

Be aware that HDFS does very poorly with small files.  It should not be treated like "regular storage".  It isn't a replacement for a real POSIX file system.
