Allen Wittenauer commented on HDFS-7991:
----------------------------------------
-1
a) Take a look at
http://wiki.apache.org/hadoop/UnixShellScriptProgrammingGuide.
b) Why are we trying to fix this at the shell level instead of at the Java
level?
c) HDFS_CHECKPOINT_BEFORE_STOP_NAMENODE
This should be HADOOP_HDFS_ blah, not HDFS_blah.
d) There's no way this passes shellcheck.
e) error messages are *way* too long for a single line.
f) where is the hadoop-env.sh documentation to match this new env var?
> Allow users to skip checkpoint when stopping NameNode
