Hello list,
I was asked whether it is a good idea to replace the M in LAMP with
Hbase as well as the P with Java-Servlet (i.e. Tomcat) so that you run
your webserver, your hbase-instance, hadoop etc. on the same machine.
Are the differences compared to a LAMP-Stack in terms of performance large?
Hi,
I think that issue is with Filesystem Configuration, as in config, it is
picking HbaseConfiguration. When I modified my output directory path to
absolute path of HDFS :
FileOutputFormat.setOutputPath(job, new Path("hdfs://master:54310/MR/stuti3"));
The MR jobs runs successfully and I am able
Hi Joey,
Thanks for pointing this. After importing "FileOutputFormat" as you suggested,
I am able to run MR job from eclipse (Windows) the only problem is I am not
able to see the output directory this code is creating. HDFS and HBase are on
Linux machine.

splits...have you looked at opentsdb

Hi everyone, i had a question about HBase.
* Background:
I'm working on analytics project and, so far, we are using MySQL as DBMS
and Hadoop for data processing and aggregation. By now, we collect data

Hi Otis,
I had super ugly experience with Amazon EC2 virtual nodes and I even found bug
reports related to Ubuntu... Problems with unpredictable "wall time" when
