Hi Team, One UDTF fails in Hive 1.0 with below stacktrace:
Caused by: java.lang.ClassCastException: org.apache.hadoop.hive.serde2.lazy.LazyString cannot be cast to org.apache.hadoop.io.Text at org.apache.hadoop.hive.serde2.objectinspector.primitive.WritableStringObjectInspector.getPrimitiveJavaObject(WritableStringObjectInspector.java:46) at org.apache.hadoop.hive.serde2.objectinspector.primitive.WritableStringObjectInspector.getPrimitiveJavaObject(WritableStringObjectInspector.java:26) at jp.co.recruit.hadoop.hive.contrib.udtf.StringSeparator.process(StringSeparator.java:117) at org.apache.hadoop.hive.ql.exec.UDTFOperator.processOp(UDTFOperator.java:108) at org.apache.hadoop.hive.ql.exec.Operator.forward(Operator.java:815) at org.apache.hadoop.hive.ql.exec.SelectOperator.processOp(SelectOperator.java:84) at org.apache.hadoop.hive.ql.exec.Operator.forward(Operator.java:815) at org.apache.hadoop.hive.ql.exec.FilterOperator.processOp(FilterOperator.java:120) at org.apache.hadoop.hive.ql.exec.Operator.forward(Operator.java:815) at org.apache.hadoop.hive.ql.exec.TableScanOperator.processOp(TableScanOperator.java:95) at org.apache.hadoop.hive.ql.exec.MapOperator$MapOpCtx.forward(MapOperator.java:157) at org.apache.hadoop.hive.ql.exec.MapOperator.process(MapOperator.java:493) ... 17 more It worksed fine in older version of Hive. Is it something triggered by the data? Or anything changed in Hive 1.0 so that LazyString can not convert to Text? -- Thanks, www.openkb.info (Open KnowledgeBase for Hadoop/Database/OS/Network/Tool)
