Re: adding a column to a groupBy (dataframe)
Hi Bruno, that's really interesting... So, to use explode, I would have to do a group by on countries and a collect_all on cities, then explode the cities, right? Am I understanding the idea right? I think this could produce the results I want. But what would be the behaviour under the hood? Does collect_all return an iterator or does it return a list? If I have a country with too many cities, would my server have to store all cities of a country in memory?

Spark logging questions
Hello, How can we dump the spark driver and executor threads information in spark application logging.? PS: submitting spark job using spark submit Regards Rohit
Getting driver logs in Standalone Cluster
Hey Guys, I am wondering what is the best way to get logs for driver in the cluster mode on standalone cluster? Normally I used to run client mode so I could capture logs from the console. Now I've started running jobs in cluster mode and obviously driver is running on worker and can't see the logs. I would like to store logs (preferably in hdfs), any easy way to do that?

Re: sparksql in sparkR?

From: ya Sent: Wednesday, June 5, 2019 11:48:17 PM To: user@spark.apache.org Subject: sparksql in sparkR? Dear list, I am trying to use sparksql within my R, I am having the following questions, could you give me some advice please? Thank you very much. 1. I connect my R and spark using the library sparkR, probably some of the members here also are R users? Do I understand correctly that SparkSQL can be connected and triggered via SparkR and used in R (not in sparkR shell of spark)? 2. I ran sparkR library in R, trying to create a new sql database and a table, I could not get the database and the table I want. The code looks like below: library(SparkR) Sys.setenv(SPARK_HOME='/Users/ya/Downloads/soft/spark-2.4.3-bin-hadoop2.7') sparkR.session(sparkHome=Sys.getenv('/Users/ya/Downloads/soft/spark-2.4.3-bin-hadoop2.7')) sql("create database learnsql; use learnsql") sql(" create table employee_tbl (emp_id varchar(10) not null, emp_name char(10) not null, emp_st_addr char(10) not null, emp_city char(10) not null, emp_st char(10) not null, emp_zip integer(5) not null, emp_phone integer(10) null, emp_pager integer(10) null); insert into employee_tbl values ('0001','john','yanlanjie 1','gz','jiaoqiaojun','510006','1353'); select*from employee_tbl; “) I ran the following code in spark-sql shell, I get the database learnsql, however, I still can’t get the table. spark-sql> create database learnsql;show databases; 19/06/06 14:42:36 INFO HiveMetaStore: 0: create_database: Database(name:learnsql, description:, locationUri:file:/Users/ya/spark-warehouse/learnsql.db, parameters:{}) 19/06/06 14:42:36 INFO audit: ugi=yaip=unknown-ip-addr cmd=create_database: Database(name:learnsql, description:, locationUri:file:/Users/ya/spark-warehouse/learnsql.db, parameters:{}) Error in query: org.apache.hadoop.hive.metastore.api.AlreadyExistsException: Database learnsql already exists; spark-sql> create table employee_tbl > (emp_id varchar(10) not null, > emp_name char(10) not null, > emp_st_addr char(10) not null, > emp_city char(10) not null, > emp_st char(10) not null, > emp_zip integer(5) not null, > emp_phone integer(10) null, > emp_pager integer(10) null); Error in query: no viable alternative at input 'create table employee_tbl\n(emp_id varchar(10) not'(line 2, pos 20) == SQL == create table employee_tbl (emp_id varchar(10) not null, ^^^ emp_name char(10) not null, emp_st_addr char(10) not null, emp_city char(10) not null, emp_st char(10) not null, emp_zip integer(5) not null, emp_phone integer(10) null, emp_pager integer(10) null) spark-sql> insert into employee_tbl values ('0001','john','yanlanjie 1','gz','jiaoqiaojun','510006','1353'); 19/06/06 14:43:43 INFO HiveMetaStore: 0: get_table : db=default tbl=employee_tbl 19/06/06 14:43:43 INFO audit: ugi=yaip=unknown-ip-addr cmd=get_table : db=default tbl=employee_tbl Error in query: Table or view not found: employee_tbl; line 1 pos 0 Does sparkSQL has different coding grammar?

Spark SQL in R?
Dear Felix and Richikesh and list, Thank you very much for your previous help. So far I have tried two ways to trigger Spark SQL: one is to use R with sparklyr library and SparkR library; the other way is to use SparkR shell from Spark. I am not connecting a remote spark cluster, but a local one. Both failed with or without hive-site.xml. I suspect the content of hive-site.xml I found online was not appropriate for this case, as the spark session can not be initialized after adding this hive-site.xml. My questions are: 1. Is there any example for the content of hive-site.xml for this case? 2. I used sql() function to call the Spark SQL, is this the right way to do it? ### ##Here is the content in the hive-site.xml:## ### javax.jdo.option.ConnectionURL jdbc:mysql://192.168.76.100:3306/hive?createDatabaseIfNotExist=true JDBC connect string for a JDBC metastore javax.jdo.option.ConnectionDriverName com.mysql.jdbc.Driver Driver class name for a JDBC metastore javax.jdo.option.ConnectionUserName root username to use against metastore database javax.jdo.option.ConnectionPassword 123 password to use against metastore database ##Here is the situation happened in R:## > library(sparklyr) # load sparklyr package > sc=spark_connect(master="local",spark_home="/Users/ya/Downloads/soft/spark-2.4.3-bin-hadoop2.7") > # connect sparklyr with spark > sql('create database learnsql') Error in sql("create database learnsql") : could not find function "sql" > library(SparkR) Attaching package: ‘SparkR’ The following object is masked from ‘package:sparklyr’: collect The following objects are masked from ‘package:stats’: cov, filter, lag, na.omit, predict, sd, var, window The following objects are masked from ‘package:base’: as.data.frame, colnames, colnames<-, drop, endsWith, intersect, rank, rbind, sample, startsWith, subset, summary, transform, union > sql('create database learnsql') Error in getSparkSession() : SparkSession not initialized > Sys.setenv(SPARK_HOME='/Users/ya/Downloads/soft/spark-2.4.3-bin-hadoop2.7') > sparkR.session(sparkHome=Sys.getenv('/Users/ya/Downloads/soft/spark-2.4.3-bin-hadoop2.7')) Spark not found in SPARK_HOME: Spark package found in SPARK_HOME: /Users/ya/Downloads/soft/spark-2.4.3-bin-hadoop2.7 Launching java with spark-submit command /Users/ya/Downloads/soft/spark-2.4.3-bin-hadoop2.7/bin/spark-submit sparkr-shell /var/folders/d8/7j6xswf92c3gmhwy_lrk63pmgn/T//Rtmpz22kK9/backend_port103d4cfcfd2c 19/06/08 11:14:57 WARN NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable Using Spark's default log4j profile: org/apache/spark/log4j-defaults.properties Setting default log level to "WARN".

Spark 2.2 With Column usage
Hi Sir, Could you please advise to fix the below issue in the withColumn in the spark 2.2 scala 2.11 joins def processing(spark:SparkSession, dataset1:Dataset[Reference], dataset2:Dataset[DataCore], dataset3:Dataset[ThirdPartyData] , dataset4:Dataset[OtherData] date:String):Dataset[DataMerge] { val referenceFiltered = dataset2.filter(.dataDate == date).filter.someColumn).select("id").toString dataset1.as("t1) join(dataset3.as("t2"), col(t1.col1) === col(t2.col1), JOINTYPE.Inner ) .join(dataset4.as("t3"), col(t3.col1) === col(t1.col1), JOINTYPE.Inner) .withColumn("new_column",lit(referenceFiltered)) .selectexpr( "id", ---> want to get this value "column1, "column2, "column3", "column4" ) } how do i get the String value ,let say the value"124567" ("referenceFiltered") inside the withColumn? im getting the withColumn output as "id:BigInt" . I want to get the same value for all the records. Note: I have asked not use cross join in the code. Any other way to fix this issue. -- Sent from: http://apache-spark-user-list.1001560.n3.nabble.com/ - To unsubscribe e-mail: user-unsubscr...@spark.apache.org
