------------------------------

[~jojochuang], thanks for your time to review.I have checked all the kind of  WRITE EC operations(the
kind of READ EC operations may not need to check the namenode whether in safemode), there
only exist two operations lack this check.Except function of addECPolicies in this issue,the
function of  FSNamesystem#removeErasureCodingPolicy may also need to do this check.But I have
already created another issue(HDFS-12066) to trace the function of removeErasureCodingPolicy.

to ensure NN is not in safemode.
