Thanks for your reply! Your comment made me realize that the table I was
trying to write onto didn't have any partition, while I was trying to write
in a specific partition:
val mapper: DelimitedRecordHiveMapper = new
DelimitedRecordHiveMapper().withColumnFields(new
Fields(colNames)).withTimeAsPartitionField("YYYY/MM/DD")
could that be the problem?
Anyway, I tried to comment out the withTimeAsPartionField and I am now
getting a totally different error, which could really be the actual issue
(as an attachment the complete stacktrace):
java.io.IOException: No FileSystem for scheme: hdfs
which makes me think I am bundling the wrong HDFS jar in the jar
application I'm building. Still, the version being bundled is hdfs 2.6.1,
while the version on the cluster is 2.7.3.2.5.5.0-157 (using HDP 2.5) which
shouldn't they be compatible?
Any suggestion?
