Hi Faisal, You need to pass through a PhoenixArray to the toBytes method, like this:
// Use Apache commons to convert from double[] to Double[] Double[] doubleArray = ArrayUtils.toObject(mydoubleArray); ptr.set( PDataType.DOUBLE_ARRAY.toBytes(new PhoenixArray(PDataType.DOUBLE, doubleArray) ); Note that underneath, the Double[] is going to stored as a double[], so it' be pretty trivial to add new constructors for PhoenixArray that take an array of a primitive type.
