Hemanth Yamijala updated HADOOP-2963:
-------------------------------------
Description:
Filed from couple of related internal bugs from Karam:
======================================
- hod should validate directory provided for hod.temp-dir if exists then it
must be a directory
- If a tempdir path is specified with '~', it is not expanded as usual.
- If there's a problem in creating a tempdir, hod exits with an error but does
not deallocate the cluster.

Filed from internal bug from Karam:
======================================
Currently hod does not check whether value provided for hod.temp-dir if exists
is a directory
For. e.g Ran hod as -:
hod -c conf/hodrc.16 -b 4 -o "allocate ~/cdir 5"
--hod.temp-dir=/a/b/c/ot
(where ot is a file not directory)
Then allocation succeeds and hadoop-site.xml for client-side contains
[
<property>
<name>dfs.client.buffer.dir</name>
<value>/a/b/c/ot/hadoopqa.4989.foo.com</value>
<description>description</description>
</property>
<property>
]
So when you run dfs client as
env HADOOP_CONF_DIR=$HOME/cdir hadoop/hadoop-0.16/bin/hadoop dfs -put data input
It fails with following error -:
[
08/01/04 11:55:25 WARN fs.AllocatorPerContext: Failed to create
/a/b/c/ot/hadoopqa.4989.foo.com
put: Could not find any valid local directory for
tmp/client-1578887916485315410
]
hod should validate directory provided for hod.temp-dir if exists then it must
be a directory
