i noticed that when i submit a job to yarn it mistakenly tries to upload
files to local filesystem instead of hdfs. what could cause this?
in spark-env.sh i have HADOOP_CONF_DIR set correctly (and spark-submit does
find yarn), and my core-site.xml has a fs.defaultFS that is hdfs, not local
filesys
Hi Koert,
Could you provide more details? Job arguments, log messages, errors, etc.

yeah sure see below. i strongly suspect its something i misconfigured
causing yarn to try to use local filesystem mistakenly.

[koert@cdh5-yarn ~]$ /usr/local/lib/spark/bin/spark-submit --class

Koert, is there any chance that your fs.defaultFS isn't setup right?

in /etc/hadoop/conf/core-site.xml:
fs.defaultFS
hdfs://cdh5-yarn.tresata.com:8020
also hdfs seems the default:
[koert@cdh5-yarn ~]$ hadoop fs -ls /
Found 5 items
drwxr-xr-x - hdfs supergroup 0 2014-06-19 12:31 /data
drwxrwxrwt - hdfs supergroup 0 2014-06-20 12:
i put some logging statements in yarn.Client and that confirms its using
local filesystem:
14/06/20 15:20:33 INFO Client: fs.defaultFS is file:///
so somehow fs.defaultFS is not being picked up from
/etc/hadoop/conf/core-site.xml, but spark does correctly pick up
yarn.resourcemanager.hostname from
ok solved it. as it happened in spark/conf i also had a file called
core.site.xml (with some tachyone related stuff in it) so thats why it
ignored /etc/hadoop/conf/core-site.xml
