Stargate sends HTTP error for rows that don't exist in Hbase table
I have been trying to look into stargate logs, but didn't find anything there or anywhere else.
Normally stargate would return a NULL value for a missing data row.
Just like we see an empty value in Result after we do get() on a row that does not exist in HBase table using the Java API.
Stargate used to work just fine but lately I get 404 and 405 Http errors. Is there a troubleshooting doc that I could look at?

Posted by Stack <st...@duboce.net>.
I talked to Andrew. 404/405 is not an error. its the way it works
when no such row (which makes sense to me given this is REST). It
used to do nulls. Thats when it was broke.

RE: Stargate sends HTTP error for rows that don't exist in Hbase
table

I think this problem could have happened because I did not stop stargate before upgrading between hbase versions or before stopping hbase?
Could that be the case? I still cannot recover from this error. Any Stargate experts out there?
