dataX -20240804-master分支

1、相关报错

Error: java.io.IOException: java.lang.RuntimeException: ORC split generation failed with exception: org.apache.orc.impl.SchemaEvolution$IllegalEvolutionException: ORC does not support type conversion from file type struct<nanos:int> (10) to reader type timestamp (10) (state=,code=0)

解决方案：

1、修改dataX源码：HdfsHelper#getColumnTypeInspectors

case TIMESTAMP:
// objectInspector = ObjectInspectorFactory.getReflectionObjectInspector(java.sql.Timestamp.class, ObjectInspectorFactory.ObjectInspectorOptions.JAVA);
objectInspector = ObjectInspectorFactory.getReflectionObjectInspector(org.apache.hadoop.hive.common.type.Timestamp.class, ObjectInspectorFactory.ObjectInspectorOptions.JAVA);
break;
case DATE:
// objectInspector = ObjectInspectorFactory.getReflectionObjectInspector(java.sql.Date.class, ObjectInspectorFactory.ObjectInspectorOptions.JAVA);
objectInspector = ObjectInspectorFactory.getReflectionObjectInspector(org.apache.hadoop.hive.common.type.Date.class, ObjectInspectorFactory.ObjectInspectorOptions.JAVA);

2、修改dataX源码：HdfsHelper#transportOneRecord
break;

case DATE:
// recordList.add(new java.sql.Date(column.asDate().getTime()));
recordList.add(org.apache.hadoop.hive.common.type.Date.ofEpochMilli(column.asDate().getTime()));
break;
case TIMESTAMP:
// recordList.add(new java.sql.Timestamp(column.asDate().getTime()));
recordList.add(org.apache.hadoop.hive.common.type.Timestamp.ofEpochMilli(column.asDate().getTime()));
break;

2、重新打包dataX安装

mvn clean package assembly:assembly -Dmaven.test.skip=true
