ORC文件读取异常

com.alibaba.datax.common.exception.DataXException: Code:[HdfsReader-00], Description:[您配置的值不合法.]. - 请确认您所读取的列配置正确！columnIndexMax 小于0,column:[]

Start with the HdfsReader path and the ORC column configuration that produces the reported DataXException. Check how columnIndexMax and the empty column value are derived for this input, then reproduce the failure with the reported configuration. Done means valid ORC column settings are accepted and the invalid configuration produces a clear, actionable error.
