首先解了决用户对象问题，创建HGGJV2READ用户，一下错误解决：

IMP-00003: ORACLE error 1917 encountered
ORA-01917: user or role 'HGGJV2READ' does not exist
IMP-00017: following statement failed with ORACLE error 1917:
 "GRANT UPDATE ON "REP_KEYWORD_WEEK_HOT" TO "HGGJV2READ""

 

对于

IMP-00032: SQL statement exceeded buffer length
IMP-00008: unrecognized statement in the export file:
网上说版本引起，也有的说导出文件或者数据库中存在坏块，后来搜多到一篇文章，在导入时候加个buffer参数，经测试问题解决，但不明原因：

imp file=95tab.dmp fromuser=show touser=show buffer=20480000 log=show.log
