question about setting SPARK_CLASSPATH IN spark_env.sh

Hi, This is about spark 0.9. I have a 3 node spark cluster. I want to add a locally available jarfile (present on all nodes) to the SPARK_CLASPATH variable in /etc/spark/conf/spark-env.sh so that all nodes can access it. Question is, should I edit 'spark-env.sh' on all nodes to add the jar ?

Re: Configuring distributed caching with Spark and YARN

I think with addJar() there is no 'caching', in the sense files will be copied everytime per job. Whereas in hadoop distributed cache, files will be copied only once, and a symlink will be created to the cache file for subsequent runs: https://hadoop.apache.org/docs/r2.2.0/api/org/apache/hadoop/fi

Re: How to set environment variable for a spark job

OK, it was working. I printed System.getenv(..) for both env variables and they gave correct values. However it did not give me the intended result. My intention was to load a native library from LD_LIBRARY_PATH, but looks like the library is loaded from value of -Djava.library.path. Value o

any distributed cache mechanism available in spark ?

I have been writing map-reduce on hadoop using PIG , and is now trying to migrate to SPARK. My cluster consists of multiple nodes, and the jobs depend on a native library (.so files). In hadoop and PIG , I could distribute the files across nodes using "-files" or "-archive" option, but I could no
