EXPERIENCE

Sears Web Intelligence Hadoop Project

June 2013 - till date

Environment : Cloudera Manager 4 version, Hadoop,Pig, Hive, SQOOP

Role : Hadoop Developer.

Description:

The purpose of the project is to store terabytes of log

information generated by the ecommerce website and extract meaning

information out of it. The solution is based on the open source BigData

s/w Hadoop .The data will be stored in Hadoop file system and processed

using Map/Reduce jobs. Which intern includes getting the raw html data from

the websites,Process the html to obtain product and pricing

information,Extract various reports out of the product pricing information

and Export the information for further processing.

This project is maily for the replatforming of the current

existing system which is running on WebHarvest a third party JAR and in

MySQL DB to a new cloud solution technology called Hadoop which can able to

process large date sets (i.e. Tera bytes and Peta bytes of data) in order

to meet the client requirements with the incresing competition from his

retailers.

Description:

In this project log datasets need to be analyzed information in semi

structured form. Most of them didn't conform to any specific schema. This

project aims to move all log data from individual servers to HDFS as the

HDFS datasets. Flume was used to move the log data periodically into HDFS.

Once the dataset is inside HDFS, Pig and Hive were used to perform various

analyses.

PMD Log Data Convert Command

Developed software for PMD Log Data Convert Command in C on HP-UX

10.x. This was because the PMD Agent cannot view Log Data directly .The Log

Data is the data which is previously gathered for the particular request

.This is to be viewed on the NT side .If the customer wants to see the Log

Data on the same Agent machine then this Log convert command first takes

the object Map of the object requested and then converts the raw formatted

data to CSV formatted text file . Did Porting of PM&D Agent and Log Data

Convert Command from HP-UX (10.0) to Solaris 2.x.

PMD Manager Data Collection

Developed support for PMD Manager Data Collection. The PMD Manager is a

sort of interface to the PMD Agent and the PMD SVC. It services the request

coming from the PMD SVC side and forwards it to the appropriate PMD Agent.

Developed software for collecting the Performance Data for various objects

on the machine on which it is running, in C on HP-UX 10.x Ported this

software from HP-UX to Solaris 2.x.

PMD Agent Log Transfer Process

The PMD Agent Log Transfer Process is an independent module which transfers

the Statistical Performance Log Data from the PMD Agent to the PMD SVC's

which request for the same. The SVC requests for the Log Data, for specific

objects which collect on PMD Agent, machines through a third party network

interface called NW-Base and the required log data is sent to the

requesting SVC by the Log Transfer Process running on PMD Agent side. The

Log Transfer process is a multi-threaded application using POSIX threads

and the NW-Base API's. This was developed in C on HP-UX 10.x. Ported this

software from HP-UX to Solaris 2.x.

PMD Manager SGM Module & Maintenance of PMD module

Did Analysis, design, coding and testing on the UNIX side. Main role was to

incorporate various modifications and fix the bugs pertaining to PM&D

Manager side as reported by the client at the Customer Site. This was done

in C on HP-UX 10.x.
