FAQ: What happens when I exceed the allocated storage space?

Answer:

Home Directory: For yourhome directory space, you will observe the following error message. writing `...': Disk quota exceeded. For example:

---

   dd: writing `/h/testuser/testfile': Disk quota exceeded

---

HDFS storage: For your HDFS space, you will receive the following exception org.apache.hadoop.hdfs.protocol.DSQuotaExceededException when running your programs or while using the hadoop utilities. For example:

   The !DiskSpace quota of /user/testuser is exceeded:
     quota=1048576 diskspace consumed=192.2m
