Eric Yang commented on HADOOP-6255:
-----------------------------------
- Yes, $PREFIX/var/lib/data-node is meant for HDFS storage.
- Yes, $PREFIX/var/lib/task-tracker is for MR spill space.
- The location are configurable by Hadoop Configuration. The conf-pseudo rpm
is design as a single node deployment, which put data in
/var/lib/hdfs/data-node, and /var/lib/mapred/task-tracker respectively.
- Yes, other services get custom log dir in var/log. Userlogs are stored as a
subdirectory as /var/log/hadoop/mapred/userlogs by the single node config rpm.
It is configurable by changing the default hadoop-env.sh.
- Stuff in lib are usually meant for C libraries, hence Owen suggested to put
jar files in share.
- The default configuration goes to /usr/share/hadoop/conf and /etc/hadoop is
symlink to conf.
- hadoop-env.sh is in /usr/share/hadoop/conf, and /etc/defaults/hadoop-env.sh
is symlinked to conf/hadoop-env.sh.
