Re: Appending and seeking files while writing

Hadoop 0.20.2 looking *inside* a file in the input path for files?
Hello, I am a newbie to hadoop, following the http://hadoop.apache.org/common/docs/r0.20.1/mapred_tutorial.html WordCount tutorial but trying update it to use the mapreduce classes instead of mapred. However I am getting the following error: 10/06/13 18:24:50 INFO mapred.JobClient: Task Id : attempt_201006131625_0023_m_00_0, Status : FAILED java.io.FileNotFoundException: 123 123 123 (No such file or directory) 123 123 123 is the first line in a file on my specified input path. Anyone have any idea what is going on? I do not run into this problem when I use the deprecated mapred classes.

See https://issues.apache.org/jira/browse/MAPREDUCE-1734 BTW, it's easier for other people to reproduce your scenario if you post your code.

Is it possible to sort values before they are sent to the reduce function?
Hi, For each key, there might be millions of values(LongWritable), but I only want to emit top 20 of these values which I want to be sorted in descending order. So is it possible to sort these values before they enter the reduce phase? Thank you in advance! Kevin
Re: Is it possible to sort values before they are sent to the reduce function?
Hi Kevin, This is a very common technique. Look for secondary sort in Tom White's HTGD (Chapter 6). You'll most likely have to write your own Partitioner and WritableComparator. -- Alex K On Sun, Jun 13, 2010 at 7:16 PM, Kevin Tse kevintse.on...@gmail.com wrote: Hi, For each key, there might be millions of values(LongWritable), but I only want to emit top 20 of these values which I want to be sorted in descending order.

Re: Caching in HDFS C API Client
I'd bet on the Linux file-cache. Assuming you wrote the file with the default replication factor of 3, there is one replica of the local- filesystem which you are reading... Try writing multiple GBs of data and randomly reading large files to blow your file-cache?

Re: Problems with HOD and HDFS
Ok, thanks Jeff. This is pretty surprising though. I would have thought many people would be in my position, where they have to use Hadoop on a general purpose cluster, and need it to play nice with a resource manager?

One red flag is that when running the allocate command, some of the variables echo-ed back look dodgy: --gridservice-hdfs.fs_port 0 --gridservice-hdfs.host localhost --gridservice-hdfs.info_port 0 These are not what I specified in the hodrc. Are the port numbers just set to 0 because I am not using an external HDFS, or is this a problem? The software versions involved are: - Hadoop 0.20.2 - Python 2.5.2 (no Twisted) - Java 1.6.0_20 - Torque 2.4.5 The hodrc file looks like this: [hod] stream = True java-home = /opt/jdk1.6.0_20 cluster = debian5 cluster-factor = 1.8 xrs-port-range = 32768-65536 debug = 3 allocate-wait-time = 3600 temp-dir= /scratch/local/dmilne/hod [ringmaster] register= True stream = False temp-dir= /scratch/local/dmilne/hod log-dir = /scratch/local/dmilne/hod/log http-port-range = 8000-9000 idleness-limit = 864000 work-dirs = /scratch/local/dmilne/hod/1,/scratch/local/dmilne/hod/2 xrs-port-range = 32768-65536 debug = 4 [hodring] stream = False temp-dir= /scratch/local/dmilne/hod log-dir = /scratch/local/dmilne/hod/log register= True java-home = /opt/jdk1.6.0_20 http-port-range = 8000-9000 xrs-port-range = 32768-65536 debug = 4 [resource_manager] queue = express batch-home = /opt/torque-2.4.5 id = torque options = l:pmem=3812M,W:X=NACCESSPOLICY:SINGLEJOB #env-vars = HOD_PYTHON_HOME=/foo/bar/python-2.5.1/bin/python [gridservice-mapred] external= False pkgs= /opt/hadoop-0.20.2 tracker_port= 8030 info_port = 50080 [gridservice-hdfs] external= False pkgs= /opt/hadoop-0.20.2 fs_port = 8020 info_port = 50070 Cheers, Dave
