Import/Export and Bulk operations

Thanks. It is happily dumping now. 

 

Just to be clear that output of this command would be files that I somehow
transfer to the destination and do the reverse (this time using -l). I
notice that the -r is a folder is it a folder for the import also?

Kevin -

 

There shouldn't be a major issue simply moving data from one place to
another if the app.config values are different.

 

Regarding the host, leave off the riak@ part.  The command would then be:

 

java -jar riak-data-migrator-0.1.3.jar  -d -a -r ~/riak-dump -h
<mailto:riak at 172.16.33.107> 172.16.33.107

I have a question about the usage of this tool. I have data locally that I
would like to export to another riak server to test the dataset. The local
"server" is a cluster and the machine I want to transfer to is just a single
machine. I notice in the documentation that there is a "warning" about the
app.config values must be the same on the two machines before this tool can
be used. Naturally since I have a cluster of 4 machines as the source and
only one machine as the destination the app.config will be different. Is
this a problem.  

The cluster of machines all have basically private addresses the destination
server has a public IP address. So I want to transfer from the source to the
destination. I am assuming that I would run the tool on one of the source
clusters and the -h option (for the host) would be the public IP address of
the single Riak server. Right?

When I run it from the source to create file dumps with:

 

java -jar riak-data-migrator-0.1.3.jar  -d -a -r ~/riak-dump -h
riak at 172.16.33.107

 

I get the following output:

 

Port not specified, using the default: 8087

HTTP port not specified, using the default: 8098

Could not connect to Riak on PB port 8087

 

So apparently it throw an error. If I look in the app.config it seems that
the port is enabled. Any idea what the problem is?

 

{riak_api, [

. . . .

            {pb_port, 8087 }

            ]},

Ok, the 0.1.4 binary download link should be working now.

The README on the git repo refers to version 0.1.4, but the link to the
download is broken...

I was wondering if there were any import/export or bulk data operations that
I was missing? I would like to "clone" a bucket from one machine to another
but I would like to avoid having to do it one item at a time.
