We run the following query: > create table test_map (other_properties map<string, string>); > insert overwrite table test_map > select other_properties from log_table where dateint = 20090825;
The other_properties column in log_table is also of the same type. We are using such a query to merge small files in our tables. We get the following array index out of bounds exceptions from all the reducers of the 2nd map-reduce job and the query failed. java.io.IOException: java.lang.ArrayIndexOutOfBoundsException: 308 at org.apache.hadoop.hive.ql.exec.ExecReducer.reduce(ExecReducer.java:202) at org.apache.hadoop.mapred.ReduceTask.runOldReducer(ReduceTask.java:465) at org.apache.hadoop.mapred.ReduceTask.run(ReduceTask.java:413) at org.apache.hadoop.mapred.Child.main(Child.java:170) Caused by: java.lang.ArrayIndexOutOfBoundsException: 308 at org.apache.hadoop.hive.serde2.lazy.LazyMap.parse(LazyMap.java:172) at org.apache.hadoop.hive.serde2.lazy.LazyMap.getMap(LazyMap.java:293) at org.apache.hadoop.hive.serde2.lazy.objectinspector.LazyMapObjectInspector.ge tMap(LazyMapObjectInspector.java:100) at org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe.serialize(LazySimpleSerDe .java:453) at org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe.serialize(LazySimpleSerDe .java:385) at org.apache.hadoop.hive.ql.exec.FileSinkOperator.process(FileSinkOperator.jav a:151) at org.apache.hadoop.hive.ql.exec.Operator.forward(Operator.java:464) at org.apache.hadoop.hive.ql.exec.ExtractOperator.process(ExtractOperator.java: 42) at org.apache.hadoop.hive.ql.exec.ExecReducer.reduce(ExecReducer.java:193) ... 3 more Is this a known issue? Our hive version is trunk version 795559 running on hadoop 0.20. Thanks a lot! Eva.
