Joshua Caplan commented on HADOOP-7682:
---
While we're creating a WinLocalFileSystem object, I found another helpful
override:
public boolean rename( Path src, Path dst ) throws IOException {
if ( exists( dst ) )
delete( dst, true );
return super.rename( src, dst );
}
This solves the problem with DistributedCache on Windows for local testing
wherein a cache file expected at
/tmp/hadoop-user/mapred/local/archive/random1_random2_random3/path/lastPath/file
ends up at
/tmp/hadoop-user/mapred/local/archive/random1_random2_random3/path/lastPath/lastPath-work--random4/file
and is invisible to the tasks that need it. Can't even express how much pain
that alleviates.

Todd Fast commented on HADOOP-7682:
---
It sounded as if he was running hadoop in pseudo-distributed or fully
distributed mode, and perhaps the way the child processes are spawned doesn't
include the patch in the classpath. A quick test to verify this theory, though
I wouldn't do this under normal running conditions, would be to put the patch
JAR in the JDK's ${JAVA_HOME}/jre/lib/ext directory, which includes it in the
classpath for all VMs. If that works, then you know that it's something to do
with the local classpath when the hadoop VMs are started. At that point, you
can further debug how the processes are spawned, or you can run in standalone
mode instead.
For standalone mode, the patch is automatically added to the classpath from the
${HADOOP_HOME}/lib directory, and if the patch is installed correctly, you
should see some logging that indicates it is working.

-
the same on hadoop 1.0.1 with win7 and cygwin 。
because just test ,so i suggest a easy workaround :
1、 alert FileUtil
mkdir $HADOOP_HOME/classes
and then alter the org.apache.hadoop.fs.FileUtil.checkReturnValue remove the
Exception .
build 、copy FileUtil.class to $HADOOP_HOME/classes 。
2 、alter classpath
add shell in $HADOOP_HOME/hadoop file ：
if [ -d $HADOOP_HOME/classes ]; then
CLASSPATH=${CLASSPATH}:$HADOOP_HOME/classes
fi
make sure this classpath is in front of $HADOOP_HOME/hadoop-core-1.*.*.jar 。
restartOK

Dave Latham commented on HADOOP-7682:
-
Here's my understanding of this issue from digging around a bit in case it's
helpful for others. I could be mistaken on some of the details.
Some time ago, RawLocalFileSystem.setPermission used to use a shell exec
command to fork a process to alter permissions of a file.
Somewhere along the 0.20 branch (I believe in the 0.20.security branch) it was
decided that this was too slow, and instead
java.io.File.set{Readable|Writable|Executable} should be used (see HADOOP-6304
for one such issue. It has a patch with the logic that wound up in FileUtil
though perhaps committed from a different patch). However the java.io.File
methods don't allow one to directly set all the permissions so the code first
has to clear permissions, then build them up again. This resulted in two
problems. First, there is a race condition when the file briefly has no
permissions even for the owner (see MAPREDUCE-2238 for more detail). Second,
Windows doesn't support clearing all permissions on the file (this JIRA).
The first problem was worked around in HADOOP-7110 (HADOOP-7432 backported it
to this branch) by using JNI native code instead. However, if the native code
is not available, then it falls back to the java.io.File methods. So, the
second problem still remains, that FileUtil.setPermission (and thus the
RawLocalFileSystem setPermission) does not work on Windows because Windows does
not have the native code implementation and also fails the java.io.File
fallback.
The issues FKorning ran into in a comment above appear to be wider than this
particular JIRA, though I may have misunderstood what led to his shorn yak.
Windows is listed as a supported platform for Hadoop, and some of our
developers use Windows as a development environment, so it's important for us
that hadoop at least functions on Windows, even if it's not as performant as
our production clusters on Linux. I noted that this is currently the highest
voted open JIRA for hadoop.
In order for it to function on Windows, I added a final fallback in
FileUtil.setPermission to revert to the older behavior of using a shell exec
fork for setPermission when the other methods fail. Perhaps it will be helpful
for others:
{code}
public static void setPermission(File f, FsPermission permission
) throws IOException {
FsAction user = permission.getUserAction();
FsAction group = permission.getGroupAction();
FsAction other = permission.getOtherAction();
// use the native/fork if the group/other permissions are different
// or if the native is available
if (group != other || NativeIO.isAvailable()) {
execSetPermission(f, permission);
return;
}
try
{
boolean rv = true;
// read perms
rv = f.setReadable(group.implies(FsAction.READ), false);
checkReturnValue(rv, f, permission);
if (group.implies(FsAction.READ) != user.implies(FsAction.READ)) {
f.setReadable(user.implies(FsAction.READ), true);
checkReturnValue(rv, f, permission);
}
// write perms
rv = f.setWritable(group.implies(FsAction.WRITE), false);
checkReturnValue(rv, f, permission);
if (group.implies(FsAction.WRITE) != user.implies(FsAction.WRITE)) {
f.setWritable(user.implies(FsAction.WRITE), true);
checkReturnValue(rv, f, permission);
}
// exec perms
rv = f.setExecutable(group.implies(FsAction.EXECUTE), false);
checkReturnValue(rv, f, permission);
if (group.implies(FsAction.EXECUTE) !=
user.implies(FsAction.EXECUTE)) {
f.setExecutable(user.implies(FsAction.EXECUTE), true);
checkReturnValue(rv, f, permission);
}
}
catch (IOException ioe)
{
LOG.warn(Java file permissions failed to set + f + to +
permission + falling back to fork);
execSetPermission(f, permission);
}
}
{code}

FKorning commented on HADOOP-7682:
--
There's a bunch of issues at work. I've patched this up locally
on my own 1.0.2-SNAPSHOT, but it takes a lot of yak-shaving to fix.
---
First you need to set up hadoop-1.0.1 including source, ant, ivy,
and cygwin with ssh/ssl and tcp_wrappers.
Then use sshd_config to create a cyg_server priviledged user.
From an admin cygwin shell, you then have to edit the /etc/passwd
file and give that user a valid shell and user home, change the
password for the user, and finally generate ssh keys for the user
and copy the user's id_rsa.pub public key into ~/.ssh/authorized_keys.
if done right you should be able to ssh cyg_server@localhost.
---
Now the main problem is a confusion between the hadoop shell scripts
that expect unix paths like /tmp, and the haddop java binaries who
interpret this path as C:\tmp.
Unfortunately, neither Cygwin symlinks nor even Windows NT Junctions
are supported by the java io filesystem. Thus the only way to get
around this is to enforce the cygwin paths to be identical to windows
paths.
I get around this by creating a circular symlink in /cygwin - /.
To avoid confusion with C: drive mappings, all my paths are relative.
This means that windows \cygwin\tmp equals cygwin's /cygwin/tmp.
For pid files use /cygwin/tmp/
For tmp file use /cygwin/tmp/haddop-${USER}/
For log files use /cygwin/tmp/haddop-${USER}/logs/
---
First the ssh slaves invocation warpper is broken because it fails to
provide the user's ssh login, which isn't defaulted to in cygwin openssh.
slaves.sh:
for slave in `cat $HOSTLIST|sed s/#.*$//;/^$/d`; do
ssh -l $USER $HADOOP_SSH_OPTS $slave $${@// /\\ } \
21 | sed s/^/$slave: /
if [ $HADOOP_SLAVE_SLEEP != ]; then
sleep $HADOOP_SLAVE_SLEEP
fi
done
Next the hadoop shell scripts are broken. you need to fix the environments
for cygwin paths in hadoop-env.sh, and then make sure this file is invoked
by both hadoop-config.sh, and finally the hadoop* sh wrapper script. For me
its JRE java invocation was also broken, so I provide the whole srcript below.
hadoop-env.sh:
HADOOP_PID_DIR=/cygwin/tmp/
HADOOP_TMP_DIR=/cygwin/tmp/hadoop-${USER}
HADOOP_LOG_DIR=/cygwin/tmp/hadoop-${USER}/logs
