I have a query which was not selecting field and the optimizer fails to evict them with the following stack trace: {noformat} FAILED: Hive Internal Error: java.lang.ArrayIndexOutOfBoundsException(-1) java.lang.ArrayIndexOutOfBoundsException: -1 at java.util.ArrayList.get(ArrayList.java:324) at org.apache.hadoop.hive.ql.optimizer.ColumnPrunerProcFactory$ColumnPrunerSelectProc.process(ColumnPrunerProcFactory.java:397) at org.apache.hadoop.hive.ql.lib.DefaultRuleDispatcher.dispatch(DefaultRuleDispatcher.java:89) at org.apache.hadoop.hive.ql.lib.DefaultGraphWalker.dispatch(DefaultGraphWalker.java:88) at org.apache.hadoop.hive.ql.optimizer.ColumnPruner$ColumnPrunerWalker.walk(ColumnPruner.java:143) at org.apache.hadoop.hive.ql.lib.DefaultGraphWalker.startWalking(DefaultGraphWalker.java:102) at org.apache.hadoop.hive.ql.optimizer.ColumnPruner.transform(ColumnPruner.java:106) at org.apache.hadoop.hive.ql.optimizer.Optimizer.optimize(Optimizer.java:87) at org.apache.hadoop.hive.ql.parse.SemanticAnalyzer.analyzeInternal(SemanticAnalyzer.java:7306) at org.apache.hadoop.hive.ql.parse.BaseSemanticAnalyzer.analyze(BaseSemanticAnalyzer.java:243) at org.apache.hadoop.hive.ql.Driver.compile(Driver.java:430) at org.apache.hadoop.hive.ql.Driver.compile(Driver.java:337) at org.apache.hadoop.hive.ql.Driver.run(Driver.java:889) at org.apache.hadoop.hive.service.HiveServer$HiveServerHandler.execute(HiveServer.java:191) at org.apache.hadoop.hive.jdbc.HiveStatement.executeQuery(HiveStatement.java:187) {noformat} The failing query reduced to the only failing part: {noformat} SELECT explodedUrls FROM ( SELECT userid, array(named_struct('date', count(*))) AS urls, count(*) AS user_lid FROM ( SELECT * FROM NicoPageViewEvent WHERE day > '20130801' ) pve GROUP BY userid ) userViewData LATERAL VIEW s_explode_pageflow(userViewData.urls) userViewDataLateralView AS explodedUrls {noformat} Adding fields make it work: {noformat} SELECT userid, explodedUrls, user_lid FROM ( SELECT userid, array(named_struct('date', count(*))) AS urls, count(*) AS user_lid FROM ( SELECT * FROM NicoPageViewEvent WHERE day > '20130801' ) pve GROUP BY userid ) userViewData LATERAL VIEW s_explode_pageflow(userViewData.urls) userViewDataLateralView AS explodedUrls {noformat} And s_explode_pageflow is a custom function which take an array of struct and split them into arrays of struct -- This message is automatically generated by JIRA.
