Re: Transferring Hive Data from One Environment to Environment
Hi, What's your environment? Is it same in both clusters? There might be some conflict jar issue if your transfer data directly from one server to another, such as, thdfsinput-->thdfsoutput. Could you please try to use tsqoopXXX component to call sqoop to transfer data from the Hadoop Distributed File System (HDFS) to a relational database management system and then call Sqoop to transfer data from a relational database management system (RDBMS) into the Hadoop Distributed File System (HDFS)? The work flow should be:HDFS(A) -->MySql(oracle...)------> Mysql(oracle....)-->HDFS(B) Or try to use distcp (Distributed Copy)command in tsystem component to see if it works. Best regards Sabrina
