(Updated Sept. 23, 2014, 2:01 a.m.) Review request for Tajo and Hyunsik Choi. Changes ------- Update patch file with the latest Tajo's code base Repository: tajo Description ------- TAJO-983: Worker should directly read Intermediate data stored in localhost rather than fetching Currently, worker always fetches all intermediate via Fetcher and than store them in local file system even though some intermediate data already are stored in local file system. It is inefficient and causes unnecessary I/O and extra storage occupation. We should improve it. https://issues.apache.org/jira/browse/TAJO-983 Diffs (updated) ----- tajo-core/src/main/java/org/apache/tajo/engine/planner/UniformRangePartition.java db12285 tajo-core/src/main/java/org/apache/tajo/engine/planner/physical/ExternalSortExec.java 700e34d tajo-core/src/main/java/org/apache/tajo/worker/Fetcher.java 4867fe4 tajo-core/src/main/java/org/apache/tajo/worker/Task.java 66e0f87 tajo-core/src/test/java/org/apache/tajo/worker/TestFetcher.java b15d523 tajo-storage/src/main/java/org/apache/tajo/storage/RawFile.java 1f57675 tajo-yarn-pullserver/src/main/java/org/apache/tajo/pullserver/PullServerAuxService.java 5f9f9e8 tajo-yarn-pullserver/src/main/java/org/apache/tajo/pullserver/TajoPullServerService.java 3fa67ae tajo-yarn-pullserver/src/main/java/org/apache/tajo/pullserver/retriever/FileChunk.java a8b424e Diff: https://reviews.apache.org/r/25242/diff/ Testing ------- Thanks, Hai Thanh Mai
