Hi folks, I research at the moment a connection over fuse and samba for hadoop-cluster. Its my private playground, but I have some issues I can't figure out why they happen. I use RHEL5.7, packetlist: rpm -qa|grep samba samba-3.0.33-3.29.el5_7.4.x86_64 samba-common-3.0.33-3.29.el5_7.4.x86_64 2 servers, one provides samba-shares and one I use as client. Samba-Server (HOST2): FuseFS:

Hello, I am trying to write the default "OrchardSprays" R data frame into HDFS using the "rhdfs" package. I want to write this data frame directly into HDFS without first storing it into any file in local file system. Which rhdfs command i should use? Can some one help me? I am very new to R and rhdfs.

Hi, I have requirement to move the data from Linux local path( ex /home/user/sample.txt) to hadoop HDFS using RODBC in R I knew that we can move the data using rhive comamnds like *rhive.put* and *rhive.get *but looking for similar commands using RODBC as well. I would appreciate for your inputs. Regards, Divakar Phoenix, USA [[alternative HTML version deleted]]

Is this a bug, or have I misunderstood the proper use of lm?

Hello List. I'm cross posting this from svn-users, as I'm not sure whether this is an CentOS specific issue.

For some reason, Rsync did not copy two specific file. Then I tried to specifically tell it to synchronize one of them and I get this result. *I* don't see any reason why to chose not to copy this file, but maybe on of you out there would see the obvious reason I am missing. dprweb> /usr/local/bin/rsync -vvv --stats -Pzrtpl --delete --password-file=/export/home/webuser/.appprod

Dear experts: Is it possible to create a new function based on stats:::model.matrix.default so that an alternative factor coding is used when the function is called instead of the default factor coding? Basically, I'd like to reproduce the results in 'mat' below, without having to explicitly specify my desired factor coding (identity matrices) in the 'contrasts.arg'. dd

hi, all: I need to back up about 50 files, the size of which won't exceed 5m, every 10~15 minutes to four remote machines. The back up command is written in a shell script file and was executed by the scheduling program with system() function. The scheduling program is implemented with c++. The command as follow: *rsync -az /home/admin/service/* admin at

Hi, all, i try to check the performance of Map/Reduce of Gluster File system. Mapper side speed is quite good and it is sometimes faster than hadoop's map job. But in the Reduce Side job is much slower than hadoop. i analyze the result and i found the primary reason of slow speed is bad performance in Merging stage. Would you have any suggestion for this issue FYI check the blog

Hi folks, I am running into a problem when calling subset() on a large data.frame. One of the columns contains strings which are used as factors. R seems to automatically factor the column when the data.frame is contstructed, and this appears to not get updated when I create a subset of the table. A minimal testcase to demonstrate the problem follows: sample <- data.frame(c("A",

I'm using rsync on an embedded powerpc platform with flash filesystem. Because of a power-cycle a local file got corrupted. This file is /flashfs/isd1, it has the correct size but wrong MD5SUM (cd5...). Using rsync to retrieve the right file (from a remote machine) fails! If I delete the file first, it works (see below). How is this possible ? --- N. van Bolhuis. # md5sum /flashfs/isd1

Hi: Recently I have some study on linux container(lxc), which is a light weight OS level virtualization. With the previous knowledge of tapdisk, I have an assumption that, I may could use the vhd for each container to seperate the storage of all containers, or even in later days, vhd is stored in distributed storage, container could be migrated.

Do we have enormous fragmentation here on our X4500 with Solaris 10, ZFS Version 10? What except zfs send/receive can be done to free the fragmented space? One ZFS was used for some month to store some large disk images (each 50GByte large) which are copied there with rsync. This ZFS then reports 6.39TByte usage with zfs list and only 2TByte usage with du. The other ZFS was used for similar
