RE: Release with PB and HA

RE: Looking for a place to start

I suggest you get a copy of Hadoop, The Definitive Guide by Tom White. I found it very informative when I was first starting out. As for sample "big data" , the book uses weather data from the NCDC. You can download it from https://github.com/tomwhite/hadoop-book/tree/master/input/ncdc/all D

RE: [jira] [Created] (HADOOP-7325) hadoop command - do not accept class names starting with a hyphen

I'm not sure if this is the intended behavior, but it sounds like this JIRA will change it. I found out the hard way that running hadoop jar myMapReduceJob.jar runs the M/R job with the current hadoop configuration. However running hadoop -jar myMarReduceJob.jar runs the M/R

RE: Why mergeParts() is not parallel with collect() on map?

RE: Configuring Heap Size for Name Node

I'm using 0.20.2. I've seen references to HADOOP_NAMENODE_OPTS, but nothing that clearly explains how to set them. Any help would be greatly appreciated. Dave Shine -Original Message- From: Hemanth Yamijala [mailto:yhema...@gmail.com] Sent: Tuesday, November 30, 2010

Configuring Heap Size for Name Node

How do I change the heap size for the Name Node (and Secondary Name Node) without changing the heap size for the data nodes, job tracker, and task trackers? Thanks, Dave Shine Sr. Software Engineer 1180 Celebration Blvd Suite 101 Celebration FL 34747 Office 321-939-5093 Mobile 407-314-0122 Fax
