Hello,
I am using visual recipes on HDFS partionned data. This morning we installed Impala (on a cluster cloudera and we set up the comunicationwith dataiku). Indeed we wanted to use the in-database engine to produce charts of all the available datasets (around 60GB). From now, we can't manage anymore the recipes.
Many thanks in advance for your help.

Hi,
You can try:
- Redeploying the client configuration (from Cloudera Manager) to all nodes, including the node on which Dataiku is installed
- Re-running the hadoop integration procedure (including the pre-check that the command line works from that node)

Hello,
thank you for your answer. We did what you proposed, but it didn't solve the problem. -
Hi,
I suggest:
1. Making sure that the various command lines (hdfs, hive, spark-shell…) work correctly from the node where Dataiku is installed. If not, it is a Hadoop configuration problem, so you should ask your Hadoop administrator or Cloudera support.
2. If it works on the command line but not in Dataiku DSS, perform a DSS diagnostic (in Administration > Maintenance) and send the result to Dataiku support http://support.dataiku.com/ along with a precise description of what doesn't work.
