Re: Hbase DeleteAll is not working

Please don't cross-post, your question is about HBase not MapReduce itself so I put mapreduce-user@ in BCC. 0.20.3 is, relatively to the age of the project, as old as my grand-mother so you should consider upgrading to 0.90 or 0.92 which are both pretty stable. I'm curious about the shell's behav

You have a typo, it's hbase.mapred.tablecolumns not hbase.mapred.tablecolumn J-D On Fri, Feb 18, 2011 at 6:05 AM, Ondrej Holecek wrote: > Hello, > > I'm testing hadoop and hbase, I can run mapreduce streaming or pipes jobs > agains text files on > hadoop, but I have a problem when I try to run

Re: Single Job to put Data into Hbase+MySQL

Do both insertions in your reducer by either not using the output formats at all or use one of them and do the other insert by hand. J-D On Wed, Oct 27, 2010 at 1:44 PM, Shuja Rehman wrote: > Hi Folks > > I am wondering if anyone has the answer of this question. I am processing > log files using

JVM reuse (was: HBase bulk load)

This is a question about straight mapreduce so I'm cross-sending the answer. To get any parallelization, you have to start multiple JVMs in the current hadoop version. Let's say you have configured your servers with mapred.tasktracker.map.tasks.maximum and mapred.tasktracker.reduce.tasks.maximum t

Re: how to load big files into Hbase without crashing?

Michael, This question should be addressed to the hbase-user mailing list as it is strictly about HBase's usage of MapReduce, the framework itself doen't have any knowledge of how the region servers are configured. I CC'd it. Uploading into an empty table is always a problem as you saw since ther
