Order By followed by "replicated" join fails while compiling MR-plan from physical plan ---------------------------------------------------------------------------------------
Key: PIG-858 URL: https://issues.apache.org/jira/browse/PIG-858 Project: Pig Issue Type: Bug Components: impl Affects Versions: 0.3.0 Reporter: Ashutosh Chauhan Fix For: 0.4.0 Consider the query: {code} A = load 'a'; B = order A by $0; C = join A by $0, B by $0; explain C; {code} works. But if replicated join is used instead {code} A = load 'a'; B = order A by $0; C = join A by $0, B by $0 using "replicated"; explain C; {code} this fails with ERROR org.apache.pig.tools.grunt.Grunt - ERROR 2034: Error compiling operator POFRJoin relevant stacktrace: {code} Caused by: java.lang.RuntimeException: org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.MRCompilerException: ERROR 2034: Error compiling operator POFRJoin at org.apache.pig.backend.hadoop.executionengine.HExecutionEngine.explain(HExecutionEngine.java:306) at org.apache.pig.PigServer.explain(PigServer.java:574) ... 8 more Caused by: org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.MRCompilerException: ERROR 2034: Error compiling operator POFRJoin at org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.MRCompiler.visitFRJoin(MRCompiler.java:942) at org.apache.pig.backend.hadoop.executionengine.physicalLayer.relationalOperators.POFRJoin.visit(POFRJoin.java:173) at org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.MRCompiler.compile(MRCompiler.java:342) at org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.MRCompiler.compile(MRCompiler.java:327) at org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.MRCompiler.compile(MRCompiler.java:233) at org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.MapReduceLauncher.compile(MapReduceLauncher.java:301) at org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.MapReduceLauncher.explain(MapReduceLauncher.java:278) at org.apache.pig.backend.hadoop.executionengine.HExecutionEngine.explain(HExecutionEngine.java:303) ... 9 more Caused by: java.lang.ArrayIndexOutOfBoundsException: -1 at org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.MRCompiler.visitFRJoin(MRCompiler.java:901) ... 16 more {code} -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
