GbaseUp跨引擎数据交换报错

 表现

gbase> insert into test_ora.t select * from TEST.t1;                                                                         

ERROR 12801 (HY000): ORA-12801: error signaled in parallel query server P000

ORA-29913: error in executing ODCIEXTTABLEFETCH callout

ORA-29400: data cartridge error

KUP-04095: preprocessor command /home/oracle/orahdfs-2.3.0/bin/hdfs_stream encountered error "which: no hadoop in (/usr/bin:/bin)

原因：oracle端/usr/bin/hadoop不存在

 解决方法

删除hadoop的软连接，重新建立ln –s /usr/ghd/8.6.2.18-206/hadoop/bin/hadoop Hadoop

注：软连接在闪烁，表示源不存在或源本身发生变更，需要重新建立软连接。
