* Correct fetchsize property name in docsDaniel Darabos2016-09-171-1/+1
| | | | | | | | | | | | | | ## What changes were proposed in this pull request? Replace `fetchSize` with `fetchsize` in the docs. ## How was this patch tested? I manually tested `fetchSize` and `fetchsize`. The latter has an effect. See also [`JdbcUtils.scala#L38`](https://github.com/apache/spark/blob/v2.0.0/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/jdbc/JdbcUtils.scala#L38) for the definition of the property.

| | | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? dapply() applies an R function on each partition of a DataFrame and returns a new DataFrame. The function signature is: dapply(df, function(localDF) {}, schema = NULL) R function input: local data.frame from the partition on local node R function output: local data.frame Schema specifies the Row format of the resulting DataFrame.

Such resulting DataFrame can be processed by successive calls to dapply(). ## How was this patch tested? SparkR unit tests.

| | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? This issue aims to fix some errors in R examples and make them up-to-date in docs and example modules. - Remove the wrong usage of `map`. We need to use `lapply` in `sparkR` if needed. However, `lapply` is private so far. The corrected example will be added later. - Fix the wrong example in Section `Generic Load/Save Functions` of `docs/sql-programming-guide.md` for consistency - Fix datatypes in `sparkr.md`. - Update a data result in `sparkr.md`. - Replace deprecated functions to remove warnings: jsonFile -> read.json, parquetFile -> read.parquet - Use up-to-date R-like functions: loadDF -> read.df, saveDF -> write.df, saveAsParquetFile -> write.parquet - Replace `SparkR DataFrame` with `SparkDataFrame` in `dataframe.R` and `data-manipulation.R`. - Other minor syntax fixes and a typo. ## How was this patch tested?

* [SPARK-10063][SQL] Remove DirectParquetOutputCommitterReynold Xin2016-04-071-33/+0
| | | | | | | | | | | | ## What changes were proposed in this pull request? This patch removes DirectParquetOutputCommitter. This was initially created by Databricks as a faster way to write Parquet data to S3. However, given how the underlying S3 Hadoop implementation works, this committer only works when there are no failures. If there are multiple attempts of the same task (e.g. speculation or task failures or node failures), the output data can be corrupted. I don't think this performance optimization outweighs the correctness issue. ## How was this patch tested? Removed the related tests also. Author: Reynold Xin <rxin@databricks.com> Closes #12229 from rxin/SPARK-10063.
* [SPARK-13579][BUILD] Stop building the main Spark assembly.Marcelo Vanzin2016-04-041-6/+1
| | | | | | | | | | | | | | | | | | | | This change modifies the "assembly/" module to just copy needed dependencies to its build directory, and modifies the packaging script to pick those up (and remove duplicate jars packages in the examples module). I also made some minor adjustments to dependencies to remove some test jars from the final packaging, and remove jars that conflict with each other when packaged separately (e.g. servlet api). Also note that this change restores guava in applications' classpaths, even though it's still shaded inside Spark. This is now needed for the Hadoop libraries that are packaged with Spark, which now are not processed by the shade plugin.

* [SPARK-12579][SQL] Force user-specified JDBC driver to take precedenceJosh Rosen2016-01-041-3/+1
| | | | | | | | | | | | | | | | Spark SQL's JDBC data source allows users to specify an explicit JDBC driver to load (using the `driver` argument), but in the current code it's possible that the user-specified driver will not be used when it comes time to actually create a JDBC connection. In a nutshell, the problem is that you might have multiple JDBC drivers on the classpath that claim to be able to handle the same subprotocol, so simply registering the user-provided driver class with the our `DriverRegistry` and JDBC's `DriverManager` is not sufficient to ensure that it's actually used when creating the JDBC connection. This patch addresses this issue by first registering the user-specified driver with the DriverManager, then iterating over the driver manager's loaded drivers in order to obtain the correct driver and use it to create a connection (previously, we just called `DriverManager.getConnection()` directly). If a user did not specify a JDBC driver to use, then we call `DriverManager.getDriver` to figure out the class of the driver to use, then pass that class's name to executors; this guards against corner-case bugs in situations where the driver and executor JVMs might have different sets of JDBC drivers on their classpaths (previously, there was the (rare) potential for `DriverManager.getConnection()` to use different drivers on the driver and executors if the user had not explicitly specified a JDBC driver class and the classpaths were different). This patch is inspired by a similar patch that I made to the `spark-redshift` library (https://github.com/databricks/spark-redshift/pull/143), which contains its own modified fork of some of Spark's JDBC data source code (for cross-Spark-version compatibility reasons). Author: Josh Rosen <joshrosen@databricks.com> Closes #10519 from JoshRosen/jdbc-driver-precedence.

* [SPARK-11089][SQL] Adds option for disabling multi-session in Thrift serverCheng Lian2015-11-171-0/+14
| | | | | | | | | | This PR adds a new option `spark.sql.hive.thriftServer.singleSession` for disabling multi-session support in the Thrift server. Note that this option is added as a Spark configuration (retrieved from `SparkConf`) rather than Spark SQL configuration (retrieved from `SQLConf`). This is because all SQL configurations are session-ized. Since multi-session support is by default on, no JDBC connection can modify global configurations like the newly added one. Author: Cheng Lian <lian@databricks.com> Closes #9740 from liancheng/spark-11089.single-session-option.
