At a high level, there are two ways to access Hudi tables in Spark. +Hudi COPY_ON_WRITE tables can be queried via Spark datasource similar to how standard datasources work (e.g: `spark.read.parquet`). +Both snapshot querying and incremental querying are supported here. Typically spark jobs require adding `--jars <path to jar>/hudi-spark-bundle_2.11:0.5.1-incubating` +to classpath of drivers and executors. Refer [building Hudi](https://github.com/apache/incubator-hudi#building-apache-hudi-from-source) for build instructions. +When using spark shell instead of --jars, --packages can also be used to fetch the hudi-spark-bundle like this: `--packages org.apache.hudi:hudi-spark-bundle_2.11:0.5.1-incubating` Review comment: use `--jars` `--packages` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
