Subject Re: Mapreduce output format killing tablet servers
Date Wed, 25 Jun 2014 18:33:41 GMT
Accumulo version   1.5.1.2.1.2.1-471
Hadoop version       2.4.0.2.1.2.1-471
tserver debug log    http://pastebin.com/BHdTkxeK

I what you mean about the memory. I am using the memory settings from the
example files
https://github.com/apache/accumulo/tree/master/conf/examples/512MB/standalone.
I also ran into this problem using the 1GB example memory settings. Each
node has 4GB RAM.

Thanks
