java 9 version

[bala vivek]

Hi,

I upgraded the jdk version to 9 and I use the pio 0.10.0-incubating version. Before the jdk upgrade the pio was working fine.

Once after the java upgrade Im getting the below error,does the pio version which i specified above will support latest version of jdk ?

PIO 0.10.0 has not been tested with java 9. Java 8 works fine. Also I’m not sure which component services (HDFS, HBase, Spark, Elasticsearch) are tested with Java 9.

In any case you should think about upgrading all, including using PIO 0.12.0 and upgrading to the highest version of all services supported. This will mean at least using Elasticsearch 5.x

hi Pat,

Is there any official page or link from PredictionIO which says about the versions of vendors and java supported by Prediction IO 0.10.0 ?

No, not since we are on PIO 0.12.0 now. You could try looking at back commits in the repo for PIO since the docs are in the same repo. 

What are you looking for? Mostly something compiled for older versions are upwardly compatible. Elasticsearch being the big exception. 0.12.0 requires ES 5.x as I said below and 0.10.0 requires something like ES 1.7.6
