从sqlserver写入hbase1700w的表，执行一段时间后报错退出。

使用的hbase11writer，但是改造加入了kerberos。时间不定，行数不定，但是都会出错。

Start with the hbase11writer path and reproduce the SQLServer-to-HBase transfer using the Kerberos setup described in the issue. Use the attached error image and vary transfer duration and row count to identify the failure; done means the long-running transfer completes without the reported exit.
