hdfs导出orc格式的hive表数据到mysql报错

hive版本是3.1，建了张测试表是orc格式的，尝试从hdfs导出数据到mysql，报错如下：com.alibaba.datax.common.exception.DataXException: Code:[HdfsReader-10], Description:[读取文件出错]. - 检查文件[hdfs://xxx/test_imsi_orc/delta_0000001_0000001_0000/_orc_acid_version]类型失败，目前支持ORC,SEQUENCE,RCFile,TEXT,CSV五种格式的文件,请检查您文件类型和文件是否正确。 - java.lang.IndexOutOfBoundsException
不知道是不是DataX的bug，
我的建表语句：
CREATE TABLE xxx.test_imsi_orc(
imsi string,
msisdn string
)row format delimited fields terminated by '|' STORED AS ORC;
job配置文件是这样的：
{
"job": {
"content": [
{
"reader": {
"name": "hdfsreader",
"parameter": {
"path": "hdfs://xx/test_imsi_orc",
"defaultFS": "hdfs://xx:8020",
"column": [
{
"index": 0,
"type": "string"
},
{
"index": 1,
"type": "string"
}
],
"fileType": "orc",
"encoding": "UTF-8",
"haveKerberos": true,
"kerberosKeytabFilePath": "xxxx",
"kerberosPrincipal": "xxxx"
}
},
"writer": {
"name": "mysqlwriter",
"parameter": {
"column": ["imsi","msisdn"],
"connection": [
{
"jdbcUrl": "jdbc:mysql://xxxx/xxxx",
"table": ["test_imsi_orc"]
}
],
"password": "xxxx",
"preSql": [],
"session": [],
"username": "xxxx",
"writeMode": "insert"
}
}
}
],
"setting": {
"speed": {
"channel": "1"
}
}
}
}

Start by reproducing the HDFSReader export with the Hive 3.1 ORC table and the supplied job configuration. Inspect the HDFSReader handling of the test_imsi_orc path and its _orc_acid_version entry, then verify the MySQL writer path. Done means the ORC table exports successfully without the file-type or IndexOutOfBoundsException error.
