Jongwook Woo commented on WHIRR-413:
------------------------------------
I also ran two times bigger data on HBase code without scan.setCaching(2000)
and it has the same error as follows because of the space limit:

/dev/sda1 9.9G 9.4G 1.2M 100% /

/dev/sda2 335G 200M 318G 1% /mnt
Thus, the error is not mainly from "scan.setCaching(2000)". If there is a way
to configure to increase the size of /dev/sda1, that is, /tmp, the issue could
be resolved.
> jobcache file is stored at /tmp/ folder so that it has out of storage error

> when I run Hadoop to read/write data from/to HBase, I got the following error
> because of the less storage space at /tmp/.
> I guess whirr is supposed to use /data/tmp/ to store jobcache file such as
> taskTracker/jobcache/job_local_0001/attempt_local_0001_m_0000xx_0/output/file.out
> because /data/tmp/ has 335GB. However, it is stored at /tmp/ that has only
