For data lifting, clojure is better. For backend infrastructure development,
scala is a better pick for most of the teams.

R/matlab has much better community in scientific computing&number crunching.
Even python has a lot of number crunching libraries. But I never heard any
friend doing scientific computation on JVM.
I'm not sure what is "data scientist", but clearly coding is just a tool for
you, instead of a job for others here. In this case you'd better stick to
the common practice in your field. Talk to your colleges, cz no one here
know your situation.
Just one question, is your computation mainly integer or floating point? JVM
's floating point is inaccurate, that is why no one in academia use it.

: Could you kindly explain why closure is better for data lifting in details?

there is no problem to use either.
the key is what project you gonna do.
you should use clojure for prototype/fast project/not known project
for long term/big team/well understood project, i definitely say scala.
clojure has one way to do things and very clean. but that way is not the
best for everything.
scala is very complex if you want to use all powers. but it really the only
thing you can use like a Haskell and at the same time use like a clean power
Java. a good plan IMO can make scala code much more efficient/reusable/
safer than clojure.
for data science stack, look at spark from Berkeley AMPLab, Handoop,
Yahoo etc. I believe it will win over storm in long run.

数据间没啥太复杂的关系,clojure简单些,上手还快。
不过两个都抵不过python吧,如果不是自己从头写新的算法。

都是理想。科学计算的基本模块从来没需要超越甚至FORTRAN77的能力。数据分析要么
用SAS,好歹SAS现在有IML了,不那么土了; 如果非要自己写算法就学C,用Rcpp和
Cython。
