[SPARK-1385] Use existing code for JSON de/serialization of BlockId `BlockId.scala` offers a way to reconstruct a BlockId from a string through regex matching. `util/JsonProtocol.scala` duplicates this functionality by explicitly matching on the BlockId type. With this PR, the de/serialization of BlockIds will go through the first (older) code path. (Most of the line changes in this PR involve changing `==` to `===` in `JsonProtocolSuite.scala`) Author: Andrew Or <andrewo...@gmail.com> Closes #289 from andrewor14/blockid-json and squashes the following commits: 409d226 [Andrew Or] Simplify JSON de/serialization for BlockId Project: http://git-wip-us.apache.org/repos/asf/spark/repo Commit: http://git-wip-us.apache.org/repos/asf/spark/commit/de8eefa8 Tree: http://git-wip-us.apache.org/repos/asf/spark/tree/de8eefa8 Diff: http://git-wip-us.apache.org/repos/asf/spark/diff/de8eefa8 Branch: refs/heads/master Commit: de8eefa804e229635eaa29a78b9e9ce161ac58e1 Parents: 11973a7 Author: Andrew Or <andrewo...@gmail.com> Authored: Wed Apr 2 10:43:09 2014 -0700 Committer: Aaron Davidson <aa...@databricks.com> Committed: Wed Apr 2 10:43:09 2014 -0700 ---------------------------------------------------------------------- .../org/apache/spark/util/JsonProtocol.scala | 77 +--------- .../apache/spark/util/JsonProtocolSuite.scala | 141 +++++++++---------- 2 files changed, 72 insertions(+), 146 deletions(-) ---------------------------------------------------------------------- http://git-wip-us.apache.org/repos/asf/spark/blob/de8eefa8/core/src/main/scala/org/apache/spark/util/JsonProtocol.scala ---------------------------------------------------------------------- diff --git a/core/src/main/scala/org/apache/spark/util/JsonProtocol.scala b/core/src/main/scala/org/apache/spark/util/JsonProtocol.scala index 346f2b7..d9a6af6 100644 --- a/core/src/main/scala/org/apache/spark/util/JsonProtocol.scala +++ b/core/src/main/scala/org/apache/spark/util/JsonProtocol.scala @@ -195,7 +195,7 @@ private[spark] object JsonProtocol { taskMetrics.shuffleWriteMetrics.map(shuffleWriteMetricsToJson).getOrElse(JNothing) val updatedBlocks = taskMetrics.updatedBlocks.map { blocks => JArray(blocks.toList.map { case (id, status) => -
