[HOD] Hadoop.tmp.dir should not be set to cluster directory
-----------------------------------------------------------
Key: HADOOP-3103
URL: https://issues.apache.org/jira/browse/HADOOP-3103
Project: Hadoop Core
Issue Type: Bug
Components: contrib/hod
Reporter: Vinod Kumar Vavilapalli
Assignee: Vinod Kumar Vavilapalli
Priority: Blocker
Fix For: 0.16.2
Currently HOD generates hadoop.tmp.dir pointing to the cluster directory(hod.clusterdir),
which users typically create in their home directories. This hadoop.tmp.dir is used on the
client side when a jar is run(org/apache/hadoop/util/RunJar.java). The user home directories
might be NFS mounted in some environments, which might result in a hit, for example when running
a jar.
So, HOD *should not* generate hadoop.tmp.dir pointing to cluster directory. Instead, it should
use hod.temp-dir, which *is* the location that dfs.client.buffer.dir uses to alleviate any
such NFS hit problems. Further, though currently hadoop.tmp.dir is not used on hadoop daemons
side, it would be good if HOD generates it on daemons side too, and thus preclude any related
problems in future.
