HBase client and server version is not compatible lead regionserver down

[????]

We recently found that regionserver down.Later, we found that because the 
client and server version is not compatible.The client version is 1.0,server 
version is 0.98.6.I want to know why this is, and whether there is a better 
protection mechanism.How to avoid this problem, because some development will 
appear this kind of mistake operation.
