Wei-Chiu Chuang commented on HDFS-13738:
----------------------------------------
:) Sorry I forgot I crafted a test case previously.
the errCode is returned, and eventually an exit code. Since the operation fails
in this case, should we set errCode to a non-zero value? Looks to me that a -1
should be returned.
Additionally, you will also want to make sure to check return code when calling
runFsck():
{code:java}
String outStr = runFsck(conf, -1, true, path, "-list-corruptfileblocks");{code}
Other than that I am +1.
> fsck -list-corruptfileblocks has infinite loop if user is not privileged.
