Re: Monet Bulk load does not work from Java after upgrade to Oct2014

Hi Dimitar, Thank you. I really appreciate it!!! I'm going to hold for a bit and wait for the merge to PDI stable release most likely. Then upgrade for both PDI and our MonetDBs. Radovan On 11/13/2014 11:39 AM, Dimitar Nedev wrote:

Hi Radovan,

The issues is due to a fix in MonetDB, which directly impacted how PDI's bulk loader uses the MonetDb JDBC connection. It is tracked in the PDI Issue tracking system here: http://jira.pentaho.com/browse/PDI-12278

More recently there was a blog post how to work around it or fix it (if you are willing to re-compile the PDI source): http://ubiquis.co.uk/pdi/monetdb-bulk-loader-and-pdi/

I hope this helps.

Best regards, Dimitar

Hello, I hate to be a bugger again. :( We use Pentaho PDI (KETTLE) for loading data from our Oracle DWH to MonetDB. After upgrade from Oct2013-SP6 to Oct2014 bulk loaders stopped working.

To be honest the problem first showed up after upgrade from Jan2014SP1 to Jan2014SP2. I was hoping it might be temporary which seems it is not.
