> If you find the server hosting META and kill -STOP its region server, it will
> eventually lose its ZK session and the master will split its logs and try to
> reassign. However, at some point along here it tries to access the old META,
> and gets SocketTimeoutExceptions, which cause it to keep retrying forever.
> Once I kill -9ed the stopped server, things came back to life.
