Subject: About running a simple wordcount mapreduce
To: mapreduce-issues@hadoop.apache.org
Hi
I am trying to run a wordcount mapreduce job on several files (<20 mb)
using two machines . I get stuck on 0% map 0% reduce.
The jobtracker log file shows the following warning:
WARN org.apache.hadoop.mapred.JobInProgress: No room for map task. Node
hadoop0.novalocal has 8791384064 bytes free; but we expect map to take
1317624576693539401
Please help me ,
Best Regards,
