ORA-01653 Unable to Extend Table AGILE.A_DW_TXN_LOG BY 128 in Tablespace AGILE_DATA3
The error is stating that either all of your tablespace data files have reached the limit of their size supported by the OS (usually 32GB each) and cannot grow, or that the storage media has physically run out of space and they cannot grow. Since the size of the tablespace appears to be about 25GB (the BYTES column) and the upper limit is 32GB (the MAXBYTES column), I'd say it is most likely that your disk is full.
That said, datapump will not automatically empty tables unless you tell it to. By default it will skip existing tables entirely and not load anything. Use the TABLE_EXISTS_ACTION parameter to tell datapump what to do in cases where tables already exist, as described here: https://docs.oracle.com/database/121/SUTIL/GUID-C9664F8C-19C5-4177-AC20-5682AEABA07F.htm#SUTIL936
