Could this error be happening because of the following? I've reinstalled PIO 0.12.0-incubating and during the installation I've observed that the screen print out read the following:
PIO_SCALA_VERSION=2.11.8 PIO_SPARK_VERSION=2.1.1 PIO_ELASTICSEARCH_VERSION=5.5.2 PIO_HADOOP_VERSION=2.7.3 However, following the installation instructions on the PIO website https://predictionio.incubator.apache.org/install/install-sourcecode/, the hadoop version installed while installing spark does not match the above requirements: $ wget http://d3kbcqa49mib13.cloudfront.net/spark-2.1.1-bin-hadoop2.6.tgz$ tar zxvfC spark-2.1.1-bin-hadoop2.6.tgz PredictionIO-0.12.0-incubating/vendors Could this be the cause of the error mentioned in my previous email? Any help will be much appreciated.
