How to patch Hadoop 0.20.2 with symbolic links patch
Hello,
I am new to hadoop. Recently, I installed Hadoop 0.20.2 and it works. I
tried to patch it with the symbolic links patch by Eli (Mr. Eli Collins):
https://issues.apache.org/jira/browse/HDFS-245
(symlink41-hdfs.patch)
I always got the error with missing Hdfs.java. This is what I did:
>cd $HADOOP_HOME
>patch -p0 < ../../patches/symlink41-hdfs.patch
can't find file to patch at input line 5
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
--------------------------
|diff --git src/java/org/apache/hadoop/fs/Hdfs.java
src/java/org/apache/hadoop/fs/Hdfs.java
|index 5d4dd41..905fea7 100644
|--- src/java/org/apache/hadoop/fs/Hdfs.java
|+++ src/java/org/apache/hadoop/fs/Hdfs.java
--------------------------
File to patch:
-------------------------------------------------------
Am I missing something here?
Thanks in advance for any info you give.
Regards,
Yujun

Hey Yujun,
Symbolic links involves a number of patches. These patches have a
number of dependencies on code in trunk (eg FileContext) so applying
to 20.2 would be a lot of work. Symbolic links are in the first
release candidate of the 21 release so probably best to check it out
if you need symlinks:
http://people.apache.org/~tomwhite/hadoop-0.21.0-candidate-0/
Thanks,
Eli
