> 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)
> at
> org.apache.hadoop.dfs.DFSClient$DFSOutputStream.newBackupFile(DFSClient.java:915)
> at org.apache.hadoop.dfs.DFSClient$DFSOutputStream.(DFSClient.java:905)
> at org.apache.hadoop.dfs.DFSClient.create(DFSClient.java:278)
> at
> org.apache.hadoop.dfs.DistributedFileSystem.createRaw(DistributedFileSystem.java:106)
> at
> org.apache.hadoop.fs.FSDataOutputStream$Summer.(FSDataOutputStream.java:58)
> at org.apache.hadoop.fs.FSDataOutputStream.(FSDataOutputStream.java:159)
> at org.apache.hadoop.fs.FileSystem.create(FileSystem.java:283)
> at org.apache.hadoop.fs.FileSystem.create(FileSystem.java:182)
> However, another reduce task scheduled on the same node didn't throw any such
> exception. Maybe this is related to HADOOP-242
