Key: HADOOP-776
URL: http://issues.apache.org/jira/browse/HADOOP-776
Project: Hadoop
Issue Type: Bug
Components: mapred
Reporter: Devaraj Das
In the sort benchmark run, I noticed a reduce task failing with the following
error/exception:
java.io.IOException: No valid local directories in property:
dfs.client.buffer.dir
at org.apache.hadoop.conf.Configuration.getFile(Configuration.java:401)

However, another reduce task scheduled on the same node didn't throw any such
exception. Maybe this is related to HADOOP-242
