Yes, you can solve the bottleneck by starting a webdav server on each
client. But this would include the burden to manage the servers etc. and
it may not be the intended use case for webdav. But we can further
discuss the architecture in the relevant issue.

Hello,
When launching a map-reduce job, I am interested in copying a certain file
to the datanodes, but not HDFS - the local file system, so I can access that
file from my job on the datanode. (The file is around 500KB, so I don't
think there will be much overhead). Is there a way to tell hadoop
Hi Jerrro,
take a look at
http://hadoop.apache.org/core/docs/r0.15.3/mapred_tutorial.html#DistributedCache
The DistributedCache looks like what you are searching for. I think the
interesting part is the example
http://hadoop.apache.org/core/docs/r0.15.3/mapred_tutorial.html#Example%3A+WordCoun
You can either pack the files with your job jar or use the distributed
cache if the file size is big. See http://wiki.apache.org/hadoop/FAQ#8.

I¹ve implemented write, but it has to wait for appends to work in Hadoop

Our strategy thus far has been to use FUSE on a single box and then NFS

Another note is we implemented the trash feature in fuse. This could be
turned on and off with ioctl. We also don¹t allow removal of certain
directories which again can be configured with ioctl. (but isn¹t yet)

I can post it again, but it doesn¹t include ioctl commands so the trash
feature cannot be configured. I can still create a flag and default it to
false. And also the directory protection isn¹t configurable so I can set a
flag to false. The main directory we protect here is /user/facebook for data
Yes, please post it again. :) Lack of trash and directory protection
shouldn't be an issue for my needs.

Still a work in progress and any help appreciated. Not much by way of

1. download and install fuse and do a modprobe fuse
2. modify fuse_dfs.c¹s Makefile to have the right paths for f

Is anyone else having the same problems as me with regard to frequently
seeing "NotServingRegionException" and "IllegalStateException: region

My setup uses

Does an hbase client java application just need a correctly configured
hbase-site.xml or does it need a hadoop-site.xml as well? By client
application I mean not a map-reduce job but something similar to the
sample application on the hbase FAQ page

Thanks,
When there are splits going on, NSREs are expected. I would say that
it is fairly unexpected for them to bubble all the way up to the
client application, though.
Is there anything else in your master or regionserver logs? Are you
running at DEBUG log level for HBase? I'd like to try and fig
I've seen the ISE's myself (HADOOP-2692). As Bryan says, the NSREs are
part of 'normal' operation; they only show if running at DEBUG level
unless we run out of retries and then the NSRE is thrown as an error.
FYI, 5M rows single-threaded will take forever to load. I'd suggest you

Yes, unless you copy all of your hadoop-site.xml to hbase-site.xml.
Hbase on startup -- server or client -- will add $HBASE_CONF_DIR and
$HADOOP_CONF_DIR to its CLASSPATH. Any hadoop-*xml and hbase-*.xml
configuration files found therein will be loaded. Hbase then uses such
as the hadoop conf
Hi,
I have some questions on the network settings.
What is the different between the following two entries?
The first one is obvious, but what does the second one mean? How is it
related to DNS?
dfs.datanode.bindAddress
0.0.0.0
the address where the datanode will listen to.

I'm actually going to be doing something similar, with Nutch. I just

everyone has to say :)

Hi all;
When I start my hbase,the error print as follows: localhost:
regionserver running as process 6893. Stop it first.
Can you tell me how to solve this problem ?Why after I stop my
hbase the regionserver still run?
Best Wishes
Its safe to 'kill' it if it won't go down. See logs to see if you can
figure why it didn't go down when master went down.
