Description
假设现在有group1和group2两个组，然后有个文件是在group2里面保存的。但是在用storageClient.delete_file(groupName,remote_filename)方法去删除文件的时候，虽然已经指定了groupName为group2，但是首次执行时仍会去访问group1，因为找不到文件就返回了22错误码。然后再执行一次时，才会去访问group2。 然后再执行一次，又会去访问group1了。
就很奇怪为什么明明已经指定了group，但是在执行的时候还是会来回的变换group访问，这是bug吗？
而如果用linux安装时带的fdfs_delete_file 功能去操作时就不会有这个问题。

Research direction
Start at the storageClient.delete_file(groupName, remote_filename) entry point and reproduce the group2 deletion against a cluster containing group1 and group2. Compare its behavior with the Linux fdfs_delete_file command; the fix is complete when an explicitly selected group is used consistently and the unexpected error 22 no longer occurs.
