Hi Nitin, I have a hive table. I am trying to sqoop export the data from the hive hdfs location. I am not using any array. And therefore I do not understand why I hit the parameter limit. It looks like sqoop exporting kind of merge all the rows. (rows * number of columns > 2100).
Thank you, Chalcy From: Nitin Pawar [mailto:[email protected]] Sent: Thursday, March 29, 2012 10:03 AM To: [email protected] Subject: Re: sqoop question - could not post- the message came back undeplivered Chalcy, from sqoop side there is no issue with number of records. this is the limitation with microsoft sql server. If you have arrays in your records etc, it might fail. Others facing the same issue have resolved using this thread on msdn http://social.msdn.microsoft.com/Forums/en-US/adodotnetentityframework/thread/145d6dfa-e523-4046-bafa-1ff0f6557634 On Thu, Mar 29, 2012 at 7:16 PM, Chalcy Raja <[email protected]<mailto:[email protected]>> wrote: I am trying to do a sqoop export (data from hdfs hadoop to database). The table I am trying to export has 2 million rows. The table has 20 fields. The sqoop command is successful if I did 10 rows till 95 rows. When I try anything more than 95, the sqoop export fails with the following error. By googling I get that this a dbms limitation. Is there anyway to configure to fix this error? I am surprised that it works for few rows. Any help is appreciated.
