HTTP status code incorrect for error conditions
-----------------------------------------------
Key: HBASE-2304
URL: https://issues.apache.org/jira/browse/HBASE-2304
Project: Hadoop HBase
Issue Type: Bug
Reporter: K M
Priority: Minor
When there is a error given in the UI/JSPs, the HTTP status code is not set
accordingly.
For example, if the page output for master.jsp is:
{{HTTP ERROR: 500
Trying to contact region server null for region , row '', but failed after 3
attempts.
Exceptions:
org.apache.hadoop.hbase.NotServingRegionException:
org.apache.hadoop.hbase.NotServingRegionException: -ROOT-,,0}}
The HTTP status code sent with the response is still "HTTP/1.1 200 OK". This
is a red herring for some types of monitoring, though it is debatable if an
HTTP status code of 4xx/5xx reflect the server state or the state of the system
being monitored. It may well be that HTTP 200 is OK, since the HTTP UI is
responsive and correctly indicating a failed HBase cluster.
