Sorry sent too early by mistake. Continuing.. I upgraded three data centers to our own checkout of 0.92.2. Two went fine, upgrade to one data center failed. Failed in the sense that ROOT and META assignment took unusually long. Panic struck I restarted master and all region servers and managed to get ROOT assigned. But META assignment got stuck badly.
The log is here : https://raw.github.com/gist/3455435/adebd118b47aa3d715201010aa09e5eb8930033c/npe_rs_0.92.2.log Notice how region server was stuck in a loop of NPE (grep processBatchCallback). There is one more NPE related to zookeeper constructor. JD was there at irc channel and he thought it could be regression.
