Jonathan Hsieh commented on HBASE-5714:
---------------------------------------
Jie, looks great and thanks for the testing output. I have only a one style
nit i'd like your thoughts on:
Can you make the calls to Runtime.getRuntime().exit(xx) happen in main instead
of the helper? If we were to write tests, the exit would make it difficult.
> Add write permissions check before any hbck run that modifies hdfs.

> We encoutered a situation where hbck was run by an under-privileged user that
> was unable to write/modify/merge regions due to hdfs perms. Unfortunately,
> this user was alerted of this after several minutes of read-only operations.
> hbck should fail early by having a write perm check and providing actionable
> advice to the hbase admin.
> Maybe something like: "Current user yy does not have write perms to <hbase
> home>. Please run hbck as hdfs user xxx"
