AFAIK, there is no documentation. I am not sure anyone has tried it before.
That said, from [1], Swift enables Apache Hadoop applications - including
MapReduce jobs, read and write data to and from instances of the OpenStack
Swift object store. And Drill uses the HDFS client library. So using Swift
through Drill should be possible.
My guess.. Create storage plugin named “swift”, copy the contents from the
“dfs” plugin. I am not sure what the contents of “swift” should be exactly; see
[1] and [2]. The parameters and values mentioned in the “Configuring” section
in [1] should be provided through the “config” map in the storage plugin (or
maybe through conf/core-site.xml in the Drill installation directory).
Something like:
{
"type": "file",
"enabled": true,
"connection": "swift://dmitry.privatecloud/out/results",
"workspaces": {
...
},
"formats": {
...
}
"config": {
...
}
}
A roundabout way could use Swift through S3 [3]. Again, I do not know the exact
configuration details.
Once you get things to work, you can also add a section to the Drill docs based
on your experience!
Thank you,
