Ted Yu commented on HBASE-7533:
-------------------------------
Both RegionMovedException and DoNotRetryIOException give clients hint on what
to do next.
I think their representation in .proto can be unified.
{code}
class RegionRelocationException extends PBException {
// ctor from server side
RegionRelocationException(RegionRelocationData message) {
super(message);
}
RegionRelocationException(byte[] bytes) {
} // ctor from server side
}
message RegionRelocationData {
required ServerName serverName = 1;
}
{code}
We can designate a special value for RegionRelocationData.serverName which
tells client that client should not retry.
