hi,

for big data and data science solution of MS SQL, how many piece of puzzle we need? I know MS SQL has R service/server included in the MS SQL installation, I don't think only one server can do the job, what is the full picture?

each need separate cost ?

I’m trying to crack my head around a key challenge at the moment. That is to increase
AI’s accuracy to be able to identify demographic age groups to plus minus 5 years
old.

Current AI settings only allow categorization of age groups of 20-24 years old,
25-29 years old…55 to 59 years old, 60 years old and above. Not plus minus.

I’m running a Data Management Platform (DMP) which collects demographic tag
information and these information are saved in Treasure Data.

I’m thinking of filtering groups of 10 years old , example 20-24, 25-29
as one group then feeding it to AI to try to increase accuracy instead of
inserting the full raw data CSV for AI to compute.

Do you think these are good ideas/methods? If yes, why. If no, any better
suggestions please?

The Data I have at the moment is not very large, average database of 100,000
users. I’m not able to increase this number any bigger at the moment.

Would be great if anyone could also advise or share on how best to
approach the challenges above and help shed some light on the challenges faced.

Many thanks in advance!

There is a partitioned(batch_date is partition)  hive  table(Table 1) with 3 columns and 1 partition

I'm trying to execute  INSERT INTO TABLE PARTITION(batch_date='2018-02-22')  select column 1, column 2, column 3 from  Table 1 where column 1 = "ABC";

It returns zero records and in hdfs it is creating 3 empty files.

Can you please suggest me a solution on how to prevent these small files  getting created in hdfs??


Note: Before running the INSERT statements I have set the below hive properties.

set hive.exec.dynamic.partition=true;
set hive.exec.dynamic.partition.mode=nonstrict;

Hello Experts,

I have created the following Hadoop Hive Script.

The script is attempting to store the results of a query into the following location:

LOCATION 'wasb://adfgetstarted@geogstoreacct.blob.core.windows.net/sampleout/';

However, I keep on getting the following error:

FAILED: ParseException line 9:0 Failed to recognize predicate 'ROW'. Failed rule: 'identifier' in table or column identifier
18/01/30 16:08:06 [main]: ERROR ql.Driver: FAILED: ParseException line 9:0 Failed to recognize predicate 'ROW'. Failed rule: 'identifier' in table or column identifier
org.apache.hadoop.hive.ql.parse.ParseException: line 9:0 Failed to recognize predicate 'ROW'. Failed rule: 'identifier' in table or column identifier

The Hive script is as follows:

[code]DROP TABLE IF EXISTS geography;
CREATE EXTERNAL TABLE geography
(
 anonid INT,
 eprofileclass INT,
 fueltypes STRING,
 acorn_category INT,
 acorn_group STRING,
 acorn_type INT,
 nuts4 STRING,
 lacode STRING,
 nuts1 STRING,
 gspgroup STRING,
 ldz STRING,
 gas_elec STRING,
 gas_tout STRING
)
ROW FORMAT DELIMITED
 FIELDS TERMINATED BY ','
STORED AS TEXTFILE
LOCATION 'wasb://adfgetstarted@geogstoreacct.blob.core.windows.net/sampleout/'
TBLPROPERTIES ("skip.header.line.count" = "1");

Create table acorn_category_frequency
 as
select acorn_category,
 count(*) as acorn_categorycount
from geography
group by acorn_category,
ROW FORMAT DELIMITED
 FIELDS TERMINATED BY ','
STORED AS TEXTFILE
LOCATION 'wasb://adfgetstarted@geogstoreacct.blob.core.windows.net/sampleout/';

Can someone please help figure out where I'm going wrong in the script?

Thanks

Hello Community,

I have created my first hql code, see below and I can't get any data to appear.. I have recently installed Sandbox. The installation comes with a few sample databases. I'm using the database called sample_07 to guide me with my own .hql code.

My hql code is as follows:

CREATE EXTERNAL TABLE mysample
(
 code STRING,
 description STRING,
 total_emp INT,
 salary INT
)
ROW FORMAT DELIMITED
 FIELDS TERMINATED BY ','
STORED AS TEXTFILE
LOCATION '/root/music'
TBLPROPERTIES ("skip.header.line.count" = "1");

Select all Open in new window

However, when I run the code using Zeppellin Notebook with the following code, I can see the tables, but no data appears

%jdbc(hive)
select * from mysample limit 14

Select all Open in new window

However, when I run the same code, with using the sample database called sample_07 both the tables and data appear.



I'm sure there is something very simple that I'm missing.

Can someone please let me know where I'm going wrong?

I'm interested in using Visual Studio in the field of BIG data and artificial intelligence.

At the moment the latest version of Visual Studio is 2017.
When is the next version due out?
What spec machine is needed for it to run smoothly in terms of processor, RAM and diskspace (and anything else that is relevant).
I found that with the Express edition, I could not use the Streamwriter.  Is this expected?

Hello,

I am new to Hadoop.  I have a question regarding yarn memory allocation.  If  we have 16GB memory in cluster,  we can have least 3 4GB cluster an keep 4 GB for other uses.  If a job needs 10 GB RAM, would it use 3 containers or  use one container and will start using the ram rest of the RAM ?
