I am currently trying to learn how can I install and configure Cloudera before using it. So I install in VirtualBox, Ubuntu 14.04, Cloudera Manager. I would like to try it on a pseudo single node (only my computer: no cluster). I manage to finish the installation. Then to Specify hosts for your CDH cluster installation ; localhost 127.0.0.1 My problem is on the "Provide SSH login credentials." step Root access to your hosts is required to install the Cloudera packages. This installer will connect to your hosts via SSH and log in either directly as root or as another user with password-less

I have a CDH 5.3 instance. I start the hive-server2 by first starting the hive-metastore and then the hive-server from command line. After this I use beeline to connect to my hive-server2 but apparently it is not able to so. Could not open connection to jdbc:hive2://localhost:10000: java.net.ConnectException: Connection refused (state=08S01,code=0) Another issue, I tried to see if the hive-server2 was listening on port 10000. I did " sudo netstat -tulpn | grep :10000 " but none of the applications came up. I also added the following property in the hive-site.xml but to no avail. Why it doesn't

We enable Namenode High Availability through Cloudera Manager, using Cloudera Manager >> HDFS >> Action > Enable High Availability >> Selected Stand By Namenode & Journal Nodes Then nameservice1 Once the whole process completed then Deployed Client Configuration. Tested from Client Machine by listing HDFS directories (hadoop fs -ls /) then manually failover to standby namenode & again listing HDFS directories (hadoop fs -ls /). This test worked perfectly. But When I ran hadoop sleep job using following command it failed $ hadoop jar /opt/cloudera/parcels/CDH-4.6.0-1.cdh4.6.0.p0.26/lib/hadoop-0

I have a simple program in Spark: /* SimpleApp.scala */ import org.apache.spark.SparkContext import org.apache.spark.SparkContext._ import org.apache.spark.SparkConf object SimpleApp { def main(args: Array[String]) { val conf = new SparkConf().setMaster("spark://10.250.7.117:7077").setAppName("Simple Application").set("spark.cores.max","2") val sc = new SparkContext(conf) val ratingsFile = sc.textFile("hdfs://hostname:8020/user/hdfs/mydata/movieLens/ds_small/ratings.csv") //first get the first 10 records println("Getting the first 10 records: ") ratingsFile.take(10) //get the number of records

I am using CDH 5.2. I am able to use spark-shell to run the commands. How can I run the file(file.spark) which contain spark commands. Is there any way to run/compile the scala programs in CDH 5.2 without sbt? Thanks in advance To load an external file from spark-shell simply do :load PATH_TO_FILE This will call everything in your file. I don't have a solution for your SBT question though sorry :-) Ziyao Li In command line, you can use spark-shell -i file.scala to run code which is written in file.scala javadba You can use either sbt or maven to compile spark programs. Simply add the spark as
