HBase thrift2 TIOError

如果HBase thrift2报：“TIOError exception: Default TException”，

这个可能是因为操作的表不存在，不一定是网络或磁盘操作异常。

HBase Thrift2偷懒了，所有异常被统一成了TIOError和TIllegalArgument两个异常，

导致调用者无法区分，而且出错信息也没能很好的带过来，增加了定位工作量。

在HBase client中为如下一个继承关系：

public class TableNotFoundException extends DoNotRetryIOException

public class DoNotRetryIOException extends HBaseIOException

public class HBaseIOException extends IOException
