While running spark ml, i am getting those warnings:
WARN BLAS: Failed to load implementation from: com.github.fommil.netlib.NativeSystemBLAS
WARN BLAS: Failed to load implementation from: com.github.fommil.netlib.NativeRefBLAS
Some information on the web states (https://stackoverflow.com/questions/43286771/spark-with-openblas-on-emr/43398522 and this http://www.spark.tc/blas-libraries-in-mllib/ ) indicates to build spark from source.
How can I easily build from source in hdp ? Is it possible to build and then replace the hdp spark folder, without breaking stuff ? Thanks.
