Bulk-Import does not really work


(Andreas Kurzac) #1

In terms of bulk import, documentation and reality don’t quite match, which means that bulk import only seems to work at the first moment.

Assumption: cluster 3-fold redundant with 3 zeros and 3 alphas

The documentation says that only the “p” directory has to be transferred to all 3 alphas and bulk import only works with a new installation, not with a running system:
“Warning Don’t use bulk loader once the Dgraph cluster is up and running. Use it to import your existing data to a new cluster.”

OK. But afterwards the DB does not work correctly, it is extremely slow and inserts lead to errors, Ratel Explorer does not know any counts, and so on…
I found out that you can “repair” the DB by setting up UIDs and timestamps by URL call:
/assign?what=uids&num=10000000
/assign?what=timestamps&num=10000000
I think ZERO usually knows the current max values, but they are probably not transferred to the production system with the “p” directory.

Is there a way to read out the max values after bulk import and to set them correctly in the production system?

Or does the “zw” directory have to be transferred to the production system in addition to the “p” directory?

Hum, can you share the commands used?

which version are you using?

dgraph bulk --version

Running in docker, container from docker hub:
dgraph/dgraph:v1.0.14

I created following script:

docker run -d --name dgraph-zero-bulk --rm \
        -p 55080:5080 \
        -v /storage/local-1/data/dgraph/bulk:/dgraph \

        dgraph/dgraph:v1.0.14 dgraph zero --my=10.20.2.12:55080 --idx 1


docker run --rm --name dgraph-bulk  -v /storage/local-1/data/dgraph/bulk:/dgraph -v /storage/global-1/data/dgraphexport:/export  dgraph/dgraph:v1.0.14 dgraph bulk -r /export/$1 -s /export/$2 --map_shards=1 --reduce_shards=1 --http localhost:8000 --zero=10.20.2.12:55080

(Michel Conrado) #4

Are you sure? this port is wrong. The default port is 5080 not 55080. If you need change it use
-o, --port_offset int "Value added to all listening port numbers". [Grpc=5080, HTTP=6080]


#5

Hi there!

I can confirm that I have same issue with 1.0.14 running directly on server.

I have setup of three zeros and three alphas with replication factor 3. When I use replication factor 1 and split data among servers in /p/0, p/1, … everything is working.


(Andreas Kurzac) #6

Yes sure: Its just a docker port mapping: dgraph needs 5080, but the access through docker is 10.20.2.12:55080. Bulk import is running while another instance is serving…


(Andreas Kurzac) #7

With replication factor 1 i only get a single directory /p/0 ?


#8

Yes, of course. I use this bulk load command:

dgraph bulk -r /migration/data.rdf.gz -s /migration/g01.schema --custom_tokenizers="/dgraph/plugins/nfd.so" --zero=1.zero.weave.local:5080 --out=/migration/out --reduce_shards=3 --map_shards=3

(Michel Conrado) #9

Not sure about it. Docker port mapping isn’t reverse proxy or something. Also If you set the wrong “my: addr” this can lead to issues in your Cluster.


(Andreas Kurzac) #10

The serving instance always uses the original ports, only one instance is running per server.
I just configured the bulk import to run on a different port, to be able to run in parallel. No problems or errors while bulk import is running.


(Michel Conrado) #11

Try with my scripts https://github.com/MichelDiz/Dgraph-Bulk-Script


(Andreas Kurzac) #12

Ah, i understand. Good idea, i didn´t think of that. I´ll try it.
Hmm… but thinking about it: I think there is a risk that your data is no longer redundant? Did you check it?


#13

You can try it. But this not solve problem with incorrect bulk import when somebody want to set up cluster with replication.


(Michel Conrado) #14

I’ve just tested locally what you mention using v1.0.14.

1 - ./dgraph zero --my=localhost:5080
2 - ./dgraph bulk -r 21million.rdf.gz -s 21million.schema --map_shards=1 --reduce_shards=1 --http localhost:8000 --zero=localhost:5080

{
	"RDFDir": "21million.rdf.gz",
	"JSONDir": "",
	"SchemaFile": "millionOLD.schema",
	"DgraphsDir": "out",
	"TmpDir": "tmp",
	"NumGoroutines": 16,
	"MapBufSize": 67108864,
	"ExpandEdges": true,
	"SkipMapPhase": false,
	"CleanupTmp": true,
	"NumShufflers": 1,
	"Version": false,
	"StoreXids": false,
	"ZeroAddr": "localhost:5080",
	"HttpAddr": "localhost:8000",
	"IgnoreErrors": false,
	"CustomTokenizers": "",
	"MapShards": 1,
	"ReduceShards": 1
}

3 - rm zeroDir
4 - ./dgraph zero --my=localhost:5080 (new zero, from scratch)
5 - cp out/0/p dgraphDir
6 - ./dgraph alpha --lru_mb 8000 --zero=localhost:5080

And is running just fine. Close and opens fast, queries are fast. No issues on logs.

Mac-Pro-de-Michel:dgraph-v1.0.14 micheldiz$ ./dgraph alpha --lru_mb 8000

One server is not problem, try to run 3 alphas and 3 zeros with replication factor 3. Copy /p to every server and you will see errors like UID is out of range (or something like that) when you will query alphas.

Okay, I’ve just tested it too (same result)


#17

You are right. I tried it one more time with my dataset on local PC and it works with last version of dGraph.

But I swear, that I’ve some issue with it few weeks ago. Maybe I used release candidate or it’s some glitch.

There was an issue long time ago with Bulk and multiple sharding. But it was solved. Never happened issues with a single shard as far I know. Since I always follow Bulk/Live issues.

I believe that any small error is the result of (before anything) misconfiguration that a user without noticing does. I do this a lot, as I’m doing a lot things at the same time, sometimes I do silly mistakes. And it’s easy to happen.

So, the case of @AndiK should be the address (--my) thing. As we can see that is possible to use only ‘p’ directory and get the results predicted in Docs. The main point is clear. Now just see where the error is in the whole process. It could also be in the process of moving the data between directories. Who knows.

I’d start from scratch tho.
