Todd Lipcon commented on HBASE-5928:
------------------------------------
Why not make it return an empty list instead? Returning null instead of empty collections is just begging for bugs like this.

Jonathan Hsieh commented on HBASE-5928:
---------------------------------------
Elliot, are you willing to make the change in the HBaseFsck#getHTableDescriptors method so that instead of being initialized to null it is initialized to empty array?
For some reason I thought I had modified that method in that exact place to return empty array already in a previous patch.

Hi Jonathan. Now the environment is being used by others. I will keep in mind, and when I could, I will double check what you said
Yes, I opened a new issue HBASE-6500, if you need, I could close that one and only trace the status here
Anyway, I will keep you posted!

[jira] [Updated] (HBASE-5928) Hbck shouldn't npe when there are no
tables.

Elliott Clark updated HBASE-5928:
---------------------------------
Attachment: HBASE-5928-0.patch
Pretty small patch.
HConnectionManager.getHTableDescriptors returns null when there are no tables.
I assumed this was expected so handling the null is needed.
