I have a script file where i'm validatig the input file and storing the validated records on HDFS.
I wanted to load data from HDFS to HBASE using pig script. So for that i have created a HBASE table and written pig script to load data from HDFS to HBASE which is working fine. Now i wanted those scripts to be wriitn in the .sh file.
I have had a 10 node HBase cluster up and running for the past 4 months. The cluster was setup on VMs in a corporate environment which I do not control, but everything has been working great...until today.
i want to access hbase table from hadoop mapreduce....i m using windowsXP and cygwin
i m using hadoop-0.20.2 and hbase-0.92.0
hadoop cluster is working fine....i am able to run mapreduce wordcount successfully on 3 pc's
hbase is also working .....i can cerate table from shell
i have tried many examples but they are not working....when i try to compile it using
I am newbie in Hadoop.I am going through the Professional Hadoop Solutions book to gain some knowledge on Hadoop and ecosystem.
I want to clarify what is main difference between HDFS and HBase.
The way i understood is like both are storage System.
