* [SPARK-8407] [SQL] complex type constructors: struct and named_structYijie Shen2015-07-029-13/+126
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a follow up of [SPARK-8283](https://issues.apache.org/jira/browse/SPARK-8283) ([PR-6828](https://github.com/apache/spark/pull/6828)), to support both `struct` and `named_struct` in Spark SQL. After [#6725](https://github.com/apache/spark/pull/6828), the semantic of [`CreateStruct`](https://github.com/apache/spark/blob/master/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/expressions/complexTypes.scala#L56) methods have changed a little and do not limited to cols of `NamedExpressions`, it will name non-NamedExpression fields following the hive convention, col1, col2 ... This PR would both loosen [`struct`](https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/functions.scala#L723) to take children of `Expression` type and add `named_struct` support.

* [SPARK-8223] [SPARK-8224] [SQL] shift left and shift rightTarek Auel2015-07-026-1/+223
| | | | | | | | | | | | | | | | | | | | | | | | | | Jira: https://issues.apache.org/jira/browse/SPARK-8223 https://issues.apache.org/jira/browse/SPARK-8224 ~~I am aware of #7174 and will update this pr, if it's merged.~~ Done I don't know if #7034 can simplify this, but we can have a look on it, if it gets merged rxin In the Jira ticket the function as no second argument. I added a `numBits` argument that allows to specify the number of bits. I guess this improves the usability. I wanted to add `shiftleft(value)` as well, but the `selectExpr` dataframe tests crashes, if I have both. I order to do this, I added the following to the functions.scala `def shiftRight(e: Column): Column = ShiftRight(e.expr, lit(1).expr)`, but as I mentioned this doesn't pass tests like `df.selectExpr("shiftRight(a)", ...` (not enough arguments exception). If we need the bitwise shift in order to be hive compatible, I suggest to add `shiftLeft` and something like `shiftLeftX` Author: Tarek Auel <tarek.auel@googlemail.com> Closes #7178 from tarekauel/8223 and squashes the following commits: 8023bb5 [Tarek Auel] [SPARK-8223][SPARK-8224] fixed test f3f64e6 [Tarek Auel] [SPARK-8223][SPARK-8224] Integer -> Int f628706 [Tarek Auel] [SPARK-8223][SPARK-8224] removed toString; updated function description 3b56f2a [Tarek Auel] Merge remote-tracking branch 'origin/master' into 8223 5189690 [Tarek Auel] [SPARK-8223][SPARK-8224] minor fix and style fix 9434a28 [Tarek Auel] Merge remote-tracking branch 'origin/master' into 8223 44ee324 [Tarek Auel] [SPARK-8223][SPARK-8224] docu fix ac7fe9d [Tarek Auel] [SPARK-8223][SPARK-8224] right and left bit shift

* [SPARK-3071] Increase default driver memoryIlya Ganelin2015-07-0115-21/+35
| | | | | | | | | | | | | | | | | | | | | | | | I've updated default values in comments, documentation, and in the command line builder to be 1g based on comments in the JIRA. I've also updated most usages to point at a single variable defined in the Utils.scala and JavaUtils.java files. This wasn't possible in all cases (R, shell scripts etc.) but usage in most code is now pointing at the same place. Please let me know if I've missed anything. Will the spark-shell use the value within the command line builder during instantiation?

| | | | | | | | | | | | | | | | | dev/merge_spark_pr.py This commit allows `dev/merge_spark_pr.py` to use personal GitHub OAuth tokens in order to make authenticated requests. This is necessary to work around per-IP rate limiting issues. To use a token, just set the `GITHUB_OAUTH_KEY` environment variable. You can create a personal token at https://github.com/settings/tokens; we only require `public_repo` scope. If the script fails due to a rate-limit issue, it now logs a useful message directing the user to the OAuth token instructions.

* [SPARK-8688] [YARN] Bug fix: disable the cache fs to gain the HDFS connection.huangzhaowei2015-07-013-5/+23
| | | | | | | | | | | | | | | | | | | | | | If `fs.hdfs.impl.disable.cache` was `false`(default), `FileSystem` will use the cached `DFSClient` which use old token. [AMDelegationTokenRenewer](https://github.com/apache/spark/blob/master/yarn/src/main/scala/org/apache/spark/deploy/yarn/AMDelegationTokenRenewer.scala#L196) ```scala val credentials = UserGroupInformation.getCurrentUser.getCredentials credentials.writeTokenStorageFile(tempTokenPath, discachedConfiguration) ``` Although the `credentials` had the new Token, but it still use the cached client and old token. So It's better to set the `fs.hdfs.impl.disable.cache` as `true` to avoid token expired.
