Role of hive.llap.execution.mode with LLAP

adel_ouzani · ‎10-01-2017

Cheers, I can not understand the role of this property with LLAP : hive.llap.execution.mode I looked for the documentation but couldn't find something useful. Can someone shed some light on this?

Cheers, When working with nested process groups and load balancing, I need to use lot of input ports to get data from higher level to the internal process group. Is there any trick to avoid doing this? Also, when I connect two nifi clusters with S2S they end up using lot of resources even if this connexion is not used. Is this normal behaviour or a know bug? is there something to tune

Hi We are thinking on having dedicated edge per project for our data lake. Each project will have a vm on which we install the required clients. Anyone is doing this ? Any problems or issues that we should be aware of with this configuration ?

@sujitha sanku Thanks I am talking about libraries that doesn't come with Spark by default like spark-csv. This code works with Spark-shell but not with Zeppelin (same thing if I use Pyspark): import org.apache.spark.sql.SQLContext val df = sqlContext.read.format("com.databricks.spark.csv").option("header", "true").option("inferSchema", "true").load("/tmp/sales.csv") df.printSchema() val selectedData = df.select("customerId", "itemId") selectedData.collect() Should I add import statement ? why this is working in Spark directly

I want to add a library and use it in Zeppelin (ex. Spark-csv). I succeeded in adding it to Spark and using it by putting my Jar in all nodes and adding spark.jars='path-to-jar' in conf/spark-defaults.conf. However when I call the library from Zeppelin it doesn't work (class not found). From my understanding Zeppelin do a Spark-submit so if the package is already added in Spark it should work. Also, I tried adding using export SPARK_SUBMIT_OPTIONS=”--jars /path/mylib1.jar,/path/mylib2.jar" to zeppelin-env.sh but same problem. Has anyone suceeded in adding libraries to Zeppelin ? have you seen this problem ?
