Thanks both for your reply, this is my /tmp folder permissions: $ ls -lh / | grep tmp drwxrwxrwt 17 root root 4.0K 2011-10-28 09:25 tmp
My HDFS folder is configured this way: $ cat /usr/local/hadoop/conf/core-site.xml <?xml version="1.0"?> <?xml-stylesheet type="text/xsl" href="configuration.xsl"?> <!-- Put site-specific property overrides in this file. --> <configuration> <property> <name>hadoop.tmp.dir</name> <value>/app/hadoop/tmp</value> <description>A base for other temporary directories.</description> </property> <property> <name>fs.default.name</name> <value>hdfs://hadoop:54310</value> <description>The name of the default file system. A URI whose scheme and authority determine the FileSystem implementation. The uri's scheme determines the config property (fs.SCHEME.impl) naming the FileSystem implementation class. The uri's authority is used to determine the host, port, etc. for a filesystem.</description> </property> </configuration> And this is the "hadoop.tmp.dir" permissions: $ ls -lh /app/hadoop total 8.0K drwxr-x--- 6 hduser hadoop 4.0K 2011-10-27 15:28 tmp drwxr-x--- 3 hduser hadoop 4.0K 2011-10-14 14:11 tmp2 Thanks and best regards! -- Josu Lazkano Barcelona Media – Centre d’Innovació
