@Neeraj Sabharwal - Sorry, I didn't get you. You mean the inbound and outbound ports on EC2? I have inbound as 5901 (for VNC server and 22 for SSH) and all for outbound.

Hi, I was trying to setup an EC2 instance to practice Hortonworks practical exam. I followed the steps mentioned in the guide. I am at step 13, where it mentioned that, I should download VNC client to connect to EC2 instance. I used public dns followed by :5901 and I am getting timeout error. Looks like it's not able to reach EC2 instance. Please let me know if any one faced the same issue. Thanks..

ok, thanks. I was looking into Cloudera sandbox and I don't see any root user under users folder on HDFS. Any idea why it's different. even it's using the YARN.

No, I have single file in data directory. First time I had created with 5 records and loaded this file into table and came back to same file, deleted all 5 records and entered 5 new records and reloaded again. I was missing the OVERWRITE keyword in the query. now it's fine. Thanks.

Thanks. What should I use if I want to override all data (I mean fresh load)?

Thanks Deepesh. Its working fine now. Does this mean, we should have root user both on the local file system and hdfs? I didn't get why we need root user on HDFS. Please help me to understand this.

Hello Friends, I am new to Hadoop and Hive. Created a simple table with one column as ID and loaded data into this table from a file that's located in local filesyste with 6 (one with NULL) records with command as "load data local inpath '/home/edureka/Desktop/data' into table emp;" Did select and it's show 5 records. Later manually changed the source file and removed all those 5 records and added 5 new records and loaded these new records without using the OVERWRITE with command "load data local inpath '/home/edureka/Desktop/data' into table emp;" Data load was successful. This time if I do select * then I am getting 18 records. 1st set is repeating twice. I don't know why it's showing like this. Am I missing any command ? pls help me to understand. Pls refer the screenshot. Thankscapture.png
