Hi
I'm new to Storm, and I would like to create a Storm topology to stream
tweets, do analysis and store on hdfs.
Is there a tutorial to do the exact same thing?
How do I start?
Thanks for the help.
PS: I have already installed Storm in HDP using Ambari.

Hi,
I'm trying to load JSON data into Hive using hcatalog JsonSerDe. I have
created the table, but when I use LOAD DATA INPATH command to load 8
records into the table. However, SELECT * shows 16 records in the table,
each record duplicated. Why is this happening?

the issue.
This should work:
CREATE EXTERNAL TABLE twitter_data(
userdata struct
userlocation:string,id:bigint,name:string,screenname:string,
tweetmessage string, createddate string)
ROW FORMAT SERDE 'org.apache.hcatalog.JsonSerDe';
Best,
Udit

First off, I'm a mainframe developer, so I don't know much about Java or
Web technology.
I work at an insurance company as a software developer. We have a website
to get quotes, raise and view claims and such.
I came to know about Hadoop and that I might be able to
leverage it to the advantage
Thanks,
Mani
Which distribution are you people using? Cloudera vs Hortonworks vs
Biginsights?
