Hi @Mayank Pandey If you have existing tables (not in ORC format), I'd recommend creating the ORC tables. Then run: insert into yourorctable
select * from yourexistingtable; Is this how you are currently inserting data?

Hi @Joshua Adeleke Can you access http://server:8088/proxy/application_1469778114081_4192 ? There should be some helpful logs that tell you exactly what happened (from the MapReduce side).

Hi @Jay Ch Great question. You must register your df1 as a temporary table like: val table = sqlContext.read.format("orc").load("/apps/hive/warehouse/yourtable")
table.registerTempTable("yourtable") and then run: val tester = sqlContext.sql("select * from yourtable");
tester.columns
You'll get the actual column names

Hi @Kyle Dunn Can you open Ambari, click on the Admin tab and Versions? Are you installing HDP on the same machines as Pivotal? Are they pointing to a separate instance of HDFS? How much data are you dealing with? I'd suggest using distcp to copy over the necessary data.

Hi @Shiv kumar Can you run the following in Python on each host (this verifies the FQDN matches up) import socket socket.getfqdn() Do you in fact get centos.test.com, centos1.test.com, centos2.test.com, centos3.test.com? Also, do you have passwordless ssh enabled from centos.test.com (I'm guessing where Ambari-server is running?) to the other hosts centos1.test.com, centos2.test.com, centos3.test.com?
