Description

In the saveToPhoenix method ProductRDDFunctions and DataFrameFunctions see if we can serialize the column metadata to the configuration object using ColumnInfoToStringEncoderDecoder.encode

and then in data.mapPartitions use ColumnInfoToStringEncoderDecoder.decode to get the list of column infos.

Currently we call PhoenixConfigurationUtil.getUpsertColumnMetadataList for each partition to get the column metadata.
