[riak] Riak binding doesn't include an slf4j Logger binding, logs nothing by default

[AhmadZia1991]

dear all , i tried to run ycsb benchmarking on Riak database i face with such problem Loading workload... Starting test. SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". SLF4J: Defaulting to no-operation (NOP) logger implementation SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

I changed setting of POM file, POM file setting is like bellow

scm:git:git://github.com/brianfrankcooper/YCSB.git

Please try to use one of our release binaries, e.g. 0.15.0: https://github.com/brianfrankcooper/YCSB/releases/tag/0.15.0

[busbey]

Looking at the Riak specific YCSB tarball, it looks like the Riak binding suffers from #1173 just like HBase 2.

[AhmadZia1991]

dear sir i am using ycsb 0.15.0 Loading workload... Starting test. SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". SLF4J: Defaulting to no-operation (NOP) logger implementation SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

[AhmadZia1991]

when i m running these commands it give me that error ./bin/ycsb load riak -P workloads/workloada ./bin/ycsb run riak -P workloads/workloada

[busbey]

As a workaround, you can download the slf4j simple logger directly:

e.g. for the riak specific tarball:

(cd lib/ && curl -O 'https://search.maven.org/remotecontent?filepath=org/slf4j/slf4j-simple/1.7.25/slf4j-simple-1.7.25.jar')

for 0.15.0 you'd end up with

[busbey]

if that's in the directory where you've installed the Riak-specific YCSB tarball, then you should be able to just run ycsb after that.

[busbey]

doing a directory listing should get you a similar listing as I posted above. If it doesn't, then back up and see what you've got different.

[AhmadZia1991]

dear sir , sorry i didnt get answer correctly , where to give this command [ ls -lah riak-binding/lib/ ]? what should be in same directory with riak ?

[AhmadZia1991]

but when i am running ( mvn install -Dskiptests ) then its ok any reason for that ?

[AhmadZia1991]

please anyone know about this issue please help me regarding this Loading workload... Starting test. SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". SLF4J: Defaulting to no-operation (NOP) logger implementation SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further detail

[AhmadZia1991]

sir you mentioned in #1173 that in case of hbase 2.0 client will need to add it , in this case where to add and how to add plz help me regarding this . thanks in advance .

[AhmadZia1991]

sir as you said in #1173 there is no logger file so please help me what to add in java file and where to add

[busbey]

please keep in mind that questions here are answered by folks volunteering their time. Be patient in your questions and I'll be patient in my answers.

[AhmadZia1991]

its ok i asked many question because at meanwhile i am searching and working on it, so at last i reach to the point which you mentioned before i think there is need of logger to add , but don't know where to past. i tried like below but it gives error.

import static com.yahoo.ycsb.db.riak.RiakUtils.createResultHashMap; import static com.yahoo.ycsb.db.riak.RiakUtils.getKeyAsLong; import static com.yahoo.ycsb.db.riak.RiakUtils.serializeTable;

/*import org.slf4j.Logger; import org.slf4j.LoggerFactory;

public class RiakKVClient extends DB {

// private static Logger logger = LoggerFactory.getLogger(RiakKVClient.class); don't worry sir i will wait when you become free then give me answer thanks and sorry for many and fast questions.

[busbey]

Let's back up for a second. I don't think you should need to run Maven.

My understanding is that you're trying to run YCSB against a Riak install. Something isn't working, but the only log message you get is the problem with getting the SLF4j logging system going.

Is that all correct?

[AhmadZia1991]

yes sir that is correct , and i tried without running mvn but still i have the same problem

[busbey]

So to confirm, you've downloaded and unpacked one of these two artifacts?

• "riak specific tarball"
• "full YCSB tarball"

If you're just going to test Riak then the smaller one at the top is probably what you want.

[busbey]

@AhmadZia1991 are you still trying to make this work? Could you confirm which of the two above artifacts you're working with?

[AhmadZia1991]

Yes sir still i am trying on it. I trying with full ycsb talbar. I trying to benchmark redis , riak , dynamodb and memcached. Others are ok just riak not giving a result and in dynamodb when i am increasing workload and work run to 200 000 then it stop and not giving result .

Okay, so you should be able to go into the directory where you unpacked the YCSB tarball and from there run this command:

(cd riak-binding/lib && curl -O 'https://search.maven.org/remotecontent?filepath=org/slf4j/slf4j-simple/1.7.25/slf4j-simple-1.7.25.jar')

And you should end up with Riak lib directory that looks like this:

-rw-r--r--   1 busbey  staff    15K Sep 11 08:18 slf4j-simple-1.7.25.jar

Once that's done, running your test with Riak should have normal logging in place.
