hbase20xsqlreader进行splitKey切分结果乱码异常

**当我在执行phoenix数据同步oracle操作时datax爆出如下异常**
`com.alibaba.datax.common.exception.DataXException: Code:[Hbasewriter-09], Description:[truncate hbase表时发生异常.]. - 查询Phoenix数据出现异常，请检查服务状态或与HBase管理员联系！ - com.aliyun.phoenix.shaded.org.apache.calcite.avatica.AvaticaSqlException: Error -1 (00000) : Error while executing SQL "select "LOANACNO","ACFLAG","BAL","PREAMTBAL","PAYOFFDATE","OVERBAL","OVERINTE","OVERAFINE","OVERBFINE","OVERGUAFEE","OVERASSUSHAREAMT","SERIOVERTERM","OVERDUEDATE","OVERDUEDAY" from "LAKE"."YD_LAKE_LOAN" where (';ZK 00023' <= LOANACNO AND LOANACNO < 'JQ|0002s\') ": Remote driver error: RuntimeException: org.apache.phoenix.exception.PhoenixParserException: ERROR 602 (42P00): Syntax error. Missing "LPAREN" at line 1, column 243. -> PhoenixParserException: ERROR 602 (42P00): Syntax error. Missing "LPAREN" at line 1, column 243. -> MissingTokenException: (null exception message)`
**通过查看源码发现datax对phoenix进行如下的主键切分**
`SELECT MIN(LOANACNO),MAX(LOANACNO) FROM LAKE.YD_LAKE_LOAN WHERE (ORGCODE IS NOT NULL AND LOANACNO IS NOT NULL);`
**执行该语句发现结果如下：**
```
+------------------+------------------+
| MIN("LOANACNO") | MAX("LOANACNO") |
+------------------+------------------+
| 00000001 | YGXX000341 |
+------------------+------------------+
```
**本地调试发现切分为如下结果：**
最终导致数据同步异常

The issue identifies the HBase 2.x SQL reader's splitKey calculation and shows the MIN/MAX query plus malformed boundary values. Start by locating that reader's splitKey handling, reproduce the Phoenix synchronization case, and verify that key values remain intact and produce valid SQL boundaries.
