Subject [jira] [Commented] (HDFS-11270) Document the missing options of NameNode bootstrap command

Mingliang Liu commented on HDFS-11270:
--------------------------------------

Thanks [~linyiqun]. I think the patch is good overall.

One minor comment is about
{quote}
-skipSharedEditsCheck option skips edits check, the edits check can ensure we have enough
edits already in the shared directory to start up, otherwise it will aborts the download of
fsimage file from active namenode.

It'd be better to have two sentences as "otherwise" case is not very straightforward. And
perhaps we don't have to mention the implementation detail of downloading fsimage from active
namenode; it also skips the possible upgrade. How about:
{quote}
-skipSharedEditsCheck option skips edits check which ensures that we have enough edits already
in the shared directory to start up from the last checkpoint on the active.

> Currently there are missing three options introduction in {{HDFSCommands.md}} of command
{{hdfs namenode [-bootstrapStandby]}}. Now this command can support {{-force}}, {{-nonInteractive}}
and a additional option {{-skipSharedEditsCheck}}. It will be better to document what's the
meaning of these options and that will let users know how to use it correctly.
