I let the import process ran overnight, only to realize next morning that it failed. I checked the alert log which in our case is under <code>/ora01/app/oracle/diag/rdbms/orcl/orcldv/alert/log.xml</code> and realized there was an error in the log: <code>ORA-1652: unable to extend temp segment by 1024 in tablespace</code>. At first this seemed weird to me but after talking to our DBA I realized this actually meant the datafile of the tablespace I was using, instead of system temp, reached its size limit.</p>
