26.7. Creating Quotas on Hadoop enabled Red Hat Gluster Storage Volume
You must not configure quota on any of the Hadoop System directories as Hadoop uses those directories for writing temporary and intermediate data. If the quota is exceeded, it will break Hadoop and prevent all users from running Jobs. Rather, you must set quotas on specific user directories so that they can limit the amount of storage capacity is available to a user without affecting the other users of the Hadoop Cluster.
