Hi All,
I have also found a similar problem.
If the regionserver and client's version was not match, the regionserver would
crash .
the crash case: regionserver's version is 1.0 and client's version is 1.1.0.

Second Enis and Heng, suggest to dig deeper into RS log and find the real
reason causing RS crash.
Best Regards,
Yu

It is highly unlikely that a client to cause the server side to abort. It
is possible that due to some other problem the regionservers are aborting.
The regionservers will reject client connection requests if there is an RPC
version mismatch.
1.x and 0.98 client and servers have been tested to be rolling upgrade
compatible (meaning that older clients can work with newer server versions
or vice versa).

HBaseAdmin has this method:
public ClusterStatus getClusterStatus() throws IOException {
where ClusterStatus has:
public String getHBaseVersion() {
return hbaseVersion;

Because a lot of development is the use of the wrong client, I think
about
how to avoid.For example, we even upgrade to 1.0 but they may use 2.0
version.

leadregionserver
down
See http://hbase.apache.org/book.html#hbase.rolling.upgrade
For example, in Rolling upgrade from 0.98.x to HBase 1.0.0, we state
that
it is possible to do a rolling upgrade between hbase-0.98.x and
hbase-1.0.0.

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.
