直接导报错：

所以尝试排除索引导出，正常。
第一步：
expdp \"/ as sysdba\" DIRECTORY=DATA_PUMP_DIR schemas=XXX PARALLEL=1 CLUSTER=N DUMPFILE=DATA-20200723.DMP logfile=DATA-20200723.LOG EXCLUDE=STATISTICS,INDEX
再尝试导出索引对象：
expdp \"/ as sysdba\" DIRECTORY=DATA_PUMP_DIR schemas=XXX PARALLEL=1 CLUSTER=N DUMPFILE=INDEX-20200723.DMP logfile=INDEX-20200723.LOG CONTENT=METADATA_ONLY EXCLUDE=STATISTICS,INDEX 报错
ORA-39126: Worker unexpected fatal error in KUPW$WORKER.UNLOAD_METADATA [OBJECT_GRANT:"XXX"]

再尝试排除指定报错的索引还是报错：
expdp \"/ as sysdba\" DIRECTORY=DATA_PUMP_DIR schemas=XXX PARALLEL=1 CLUSTER=N CONTENT=METADATA_ONLY DUMPFILE=xxx_1.DMP logfile=xxx-1.LOG EXCLUDE=STATISTICS EXCLUDE=INDEX:\"IN ('IDX_TUBE_FLDTEMPFLAG', 'IDX_DX_FLDTEMPFLAG', 'IDX_ENTITY_CONFIG_FLDBUSITYPE', 'IDXB_EXP_SQL_ISVALIDE', 'IDX_EXP_ENTITY_POLLTYPE', 'IDX_EXP_ENTITY_IMMEDIATE')\"
最后再执行下面操作处理解决：
把表，DB_LINK,GRANT都排除再导出（因为第一步除了索引，其它对象都已经包含了，所以能排除越多越好，这边只是简单排除了一下）
第二步：
expdp \"/ as sysdba\" DIRECTORY=DATA_PUMP_DIR schemas=XXX PARALLEL=1 CLUSTER=N DUMPFILE=INDEX-20200723.DMP logfile=INDEX-20200723.LOG CONTENT=METADATA_ONLY EXCLUDE=STATISTICS,TABLE,DB_LINK,GRANT
做IMPDP恢复的时候只需要先导入第一步，再导入第二步即可。
