i have tried both of the methods you side, but the problem= still exists. Thanks all the same. by the way, my hadoop version is 2.2.0,= so the parameter=C2=A0=C2=A0"mapreduce.map.memory.mb =3D3072&= quot; added to mapred-site.xml maybe has no effect. I have looked for this = parameter in the document of hadoop, but did not found it.
