Subject Mapreduce output format killing tablet servers
Date Wed, 25 Jun 2014 18:01:14 GMT
I am trying to create an inverted text index for a table using accumulo
input/output format in a java mapreduce program.  When the job reaches the
reduce phase and creates the table / tries to write to it the tablet
servers begin to die.

Now when I do a the tablet servers start for about a minute
and then die again. Any idea as to why the mapreduce job is killing the
tablet servers and/or how to bring the tablet servers back up without

This is on a 12 node cluster with low quality hardware.

The java code I am running is here

The log files on each tablet server only display the startup information,
no errors. The log files on the master server show these errors
