Hi all,

Spark to hive give the expected results but launch the error : ERROR Spark to Hive 0:232 [org.apache.hadoop.hdfs.KeyProviderCache, Could not find uri with key [dfs.encryption.key.provider.uri] to create a keyProvider !!]

Best regards,

Fabien

Hi Fabien,

we have seen this message a couple of times (on Cloudera I believe?), but the KNIME workflow still worked asexpected. So, unless the KNIME workflow does not work correctly, I would say don't worry about the message :)

By the way, this seems to be an HDFS bug: https://issues.apache.org/jira/browse/HDFS-7931

Best regards,

Björn
