Adding jars o Tableau

Hi ,

I have a seqence file in HDFS which has a custom writable as value.

When i am trying to access this file in hive , i created a deserializer ,build a jar for it and added that jar through hive .

hive>add jar jar_name;

Then i am able to query that sequence file through hive.

Now How do i achieve the same through tableau?

Does it have the possibility of adding the jar to its classpath or is there anr other approach?

Please help me at the earliest.

Thanks,Subbu

Endeca vs Tableau

HI I am new to both the Tableau and Oracle Endeca.

I am trying to find which is much better to use .

So the below are my questions.

1.Can tableau act as a cluster ? Hadoop or hive have a cluster to manage big data ,So can tableau handle big data , if it can where does it store such data, as far i an see it is like a software running on a single system or a server. We cant have this single system to be of the same size as the actual cluster.So i assuming that there is a limit to how much data the tableau can handle.

2.So from my first question i am thinking that endeca of oracle is better as it has both data integration and also visualization(i am thinking that tableau can do only visualization)as it has a concept of cluster like HDFS.

3.does the tableau has in memory calcualtions ,if so should'nt be there a limit to much data it can handle at a time

4.Also please tell the pro and cons of using tableau over endeca or the other way.

Please help me in this issue at the earliest

Thanks,

Subbu
