Hello everyone, I'm having trouble with the entries in wmf.wdqs_extract on 23.08.2017, specifically the hours 9-17. The call hive -e "insert overwrite local directory 'temp' row format delimited fields terminated by '\t' select uri_query, uri_path, user_agent, ts, agent_type, hour, http_status from wmf.wdqs_extract where uri_query<>\"\" and year='2017' and month='8' and day='23' and hour='8'" works fine, as do all hours in 0-8 and 18-23, but if I change hour to anything between 9 and 17 it fails with the following message: Error: java.lang.RuntimeException: Error in configuring object at org.apache.hadoop.util.ReflectionUtils.setJobConf(ReflectionUtils.java:109) at org.apache.hadoop.util.ReflectionUtils.setConf(ReflectionUtils.java:75) at org.apache.hadoop.util.ReflectionUtils.newInstance(ReflectionUtils.java:133) at org.apache.hadoop.mapred.MapTask.runOldMapper(MapTask.java:449) at org.apache.hadoop.mapred.MapTask.run(MapTask.java:343) at org.apache.hadoop.mapred.YarnChild$2.run(YarnChild.java:164) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:421) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1796) at org.apache.hadoop.mapred.YarnChild.main(YarnChild.java:158) Caused by: java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.apache.hadoop.util.ReflectionUtils.setJobConf(ReflectionUtils.java:106) ... 9 more Caused by: java.lang.RuntimeException: Error in configuring object at org.apache.hadoop.util.ReflectionUtils.setJobConf(ReflectionUtils.java:109) at org.apache.hadoop.util.ReflectionUtils.setConf(ReflectionUtils.java:75) at org.apache.hadoop.util.ReflectionUtils.newInstance(ReflectionUtils.java:133) at org.apache.hadoop.mapred.MapRunner.configure(MapRunner.java:38) ... 14 more Caused by: java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.apache.hadoop.util.ReflectionUtils.setJobConf(ReflectionUtils.java:106) ... 17 more Caused by: java.lang.RuntimeException: Map operator initialization failed at org.apache.hadoop.hive.ql.exec.mr.ExecMapper.configure(ExecMapper.java:147) ... 22 more Caused by: java.lang.RuntimeException: Hive internal error: conversion of string to array<string>not supported yet. at org.apache.hadoop.hive.serde2.objectinspector.ObjectInspectorConverters$ListConverter.<init>(ObjectInspectorConverters.java:313) at org.apache.hadoop.hive.serde2.objectinspector.ObjectInspectorConverters.getConverter(ObjectInspectorConverters.java:158) at org.apache.hadoop.hive.serde2.objectinspector.ObjectInspectorConverters$StructConverter.<init>(ObjectInspectorConverters.java:374) at org.apache.hadoop.hive.serde2.objectinspector.ObjectInspectorConverters.getConverter(ObjectInspectorConverters.java:155) at org.apache.hadoop.hive.serde2.objectinspector.ObjectInspectorConverters$StructConverter.<init>(ObjectInspectorConverters.java:374) at org.apache.hadoop.hive.serde2.objectinspector.ObjectInspectorConverters.getConverter(ObjectInspectorConverters.java:155) at org.apache.hadoop.hive.ql.exec.MapOperator.initObjectInspector(MapOperator.java:199) at org.apache.hadoop.hive.ql.exec.MapOperator.setChildren(MapOperator.java:355) at org.apache.hadoop.hive.ql.exec.mr.ExecMapper.configure(ExecMapper.java:116) ... 22 more Can anybode help me out with this?
