I need help resolving this issue:
When i run my program to call one of the methods from a library, i get following error:
SLF4J: Class path contains multiple SLF4J bindings.

I am running a spark application using yarn in cloudera.
Spark version: 2.1
I get the following error:
SLF4J: Class path contains multiple SLF4J bindings. SLF4J: Found

I managed to solve it by verifyning that the spark version configured in SPARK_HOME variable matches the hadoop version installed in cloudera.
From the following link https://spark.apache.org/downloads.html you can download the suitable version for your required hadoop.
The haddop version in cloudera can by found by:
$ hadoop version
I encounter the same issue while trying to start a Spark job using Yarn Rest API.
And the reason was that the environment variable SPARK_YARN_MODE was missing. Adding this env var, everything works fine :
export SPARK_YARN_MODE=true
I followed this
https://github.com/apache/spark/blob/master/docs/README.md
to build spark docs,but it hangs on:
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.
after half an hour,no further info got printed out.I tried to add slf4j-simple-1.7.12.jar into spark/lib_managed/jars,then rerun
jekyll build
still hang on these messages,how to solve the problem?
For me the solution was adding Logback Classic Module to the classpath:
http://mvnrepository.com/artifact/ch.qos.logback/logback-classic/1.1.7
and removing any other implementations of StaticLoggerBinder.
There's an explanation in the Spark documentation:
http://sparkjava.com/documentation#how-do-i-enable-logging
You might have seen this message when starting Spark:
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.Copy
To enable logging, just add the following dependency to your project:
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>1.7.21</version>
</dependency>
For Gradle, check this thread for more details:
How to set SLF4J in IntelliJ with Gradle
Then you'll might need to configure slf4j properly, by creating a config file, but that's a different topic. Check this and this if that's the case.
I am trying to create a log file while using pyspark, but I am getting the following error message:
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 have added the jar files in my class-path, but I still get this error. Anyway I can sort this out. I even tried to pass the jar file as arguments in driver-class-path, but still I get the same error.
I am using HDP2.3 and trying to use Spark(1.3.1) as the execution engine for running hive queries.
spark-assembly jar is also available in the hive/lib folder.
I am able to run the query in spark-master: local but facing the below issue when using spark-master: yarn-cluster.
command run,
hive -e "set hive.execution.engine=spark; set
spark.master=yarn-cluster; select count(*) from db_name.table_name;"
output,

Any help on debugging the issue is much appreciated.
I don't think queries can be executed in yarn-cluster mode.
You can run interactive queries in local and yarn-client mode only
I have followed this (http://sujitpal.blogspot.in/2012/09/learning-mahout-clustering.html) link and created initial clusters and k-means clusters as mentioned in below link but when i tried to dump the clusters to local system i am getting below error

Please suggest me how to get this
Thanks
I used below command and its working
mahout clusterdump -dt sequencefile -d vectorfiles/dictionary.file-0 -i kmeans-clusters/clusters-1-final -o result.txt -b 10 -n 10
